Cancer identifies a disease that arises due to the cells abnormally dividing then later attacking other body tissues. The cancerous cells usually extend to other parts of the body via the lymphatic or blood system. The environmental causes of cancer refer to those factors that do not relate to inherited or hereditary factors. Cancer has been termed to be one of the major death causes with over two-thirds of it arising from environmental factors. With the knowledge that various environment agents can cause cancer, it is vital for people to change their lifestyles and environmental activities that are likely to cause cancer.

When determining what factors in the environmental cause cancer, various factors can be attributed to it. The causes of cancer can either be tied to the external or personal environment. The personal environment factors likely to cause the cancer include lifestyle preferences like tobacco and diet. Tobacco has been said to be the cause of about one third of deaths caused by cancer yearly. Ultra violet rays arising from sunlamps, the sun itself or tanning beds are known to cause various kinds of skin cancer like melanoma. The environmental causes of cancer arise from lifestyle factors and exposure to water or air agents. Some of the different environmental agents likely to cause cancer include occupational exposures, ionizing radiation, chemicals, medical drugs and even alcohol.

Over years, epidemiologists have estimated the new cancer cases and death percentages caused by environmental agents. For instance, about 30% cancer deaths are attributed to tobacco. Other cancer cases are caused by water and air pollution, occupations, medical procedures and medicine. When establishing what environmental factors cause cancer, it is important to bear in mind some of these environmental factors. Another environmental cause of cancer is ionizing radiation. Exposure to radiation from sources like radon, cosmic rays, atomic bombs, nuclear bomb tests done on the ground and X-ray is a cause of cancer.

Carcinogens identify substances believed to increase the risk of developing cancer. To make out what causes cancer, bear in mind environmental carcinogens. In some instances, carcinogens damage the DNA directly while in some, the cause is indirect. This explains why not each exposure to a carcinogen leads to cancer. The extent and intensity of exposure to ecological carcinogens determines the chances of developing cancer. Some ecological carcinogens include chemicals, infectious agents, and air pollution. Exposure to particular chemicals, parasites, and bacteria are known risk factors for various cancer types.

The main environmental causes of cancer are generally associated with the personal and external environment. Radiation, sun exposure and environmental pollutants are some of the external environmental cancer causes. Individuals’ ways of life ranging from the diet to the elements one uses or is exposed to like tobacco and nutrition have been proven to cause cancer.

You or a loved one has previously noticed some of the disconcerting symptoms of cancer and been diagnosed with a malignancy.

If you’re now fighting that cancer and are curious about immune system supplements, both clinical and natural, keep reading for an overview of some of the most popular methods.

BRMs (Biologic Response Modifiers)

Biologic response modifiers basically affect the way in which your immune system responds to certain defenses and attacks. They can also help restore and regenerate damage immune system cells. They are a form of immunotherapy, vaccine and immune-boosting supplement all in one.

The most commonly used type of biologic response modifiers is interferon. Interferon is a protein molecule that can help fight off certain diseases, like cancer. However, for treatment purposes, synthetic interferon is created in a lab and then administered to the patient to supplement the immune system. Interferon won’t cure cancer, but it will improve life spans and help control the disease.

Vitamin Supplements

There are mountains of studies that prove certain foods and vitamins are critical immune system supplements and help to restore the body after cancer while also preventing it.

The most expansive and possibly the most controversial studies were conducted by Linus Pauling. One of Pauling’s more interesting works compared the longevity and success rates of individuals with similar types of cancer and who were of similar ages.

Pauling placed one hundred of these patients on high doses of Vitamin C and left the remaining thousand with no vitamin therapy whatsoever. The individuals placed on the Vitamin C therapy lived significantly longer than the patients who received no vitamin therapy.

One of the biggest advantages behind Vitamin C therapy is that there are few side effects or downsides. Vitamin C is not toxic, it’s water-soluble and excesses are simply eliminated from the body. It’s one of the immune system supplements that has many benefits but few drawbacks.

Diet

Diet all by itself won’t cure cancer, but it can help slow it down, improve recovery and possibly prevent it. Nutrition is a major part of how well your body recovers after cancer, the strength of your immune system and how you deal with cancer and the cancer treatments.

One example of eating for the benefit of the immune system is all-organic diets, which are growing in popularity. Organic foods are foods that are all natural, have not been irradiated and have no chemical additives. For people trying to heal cancer, chemical additives are thought to be just one more foreign substance that can stress the body’s system.

That means instead of working hard to process and deal with harsh chemicals, your body is free to fight off cancer cells or simply focus on healing itself.

Whenever a person receives a diagnosis of cancer of any kind, you inevitably think backward to prior recognition of abnormal symptoms that may have been missed and then forward with hopefulness to cancer treatments. Spotting symptoms in their early stages usually leads to positive results.

In the U.S., over 90 percent of breast cancer diagnoses happen during the early breast cancer stages. Early detection is good news for the patient as it often translates to effective treatment.

However, this is only a portion of the whole clinical picture. Various characteristics, like lymph node engagement and receptor status, can help prognosticate outcome and aid in choosing a treatment selection, making them critical factors for survival.

Though breast cancer rates are increasing in North America and the United Kingdom, the fatality rate is falling. This declining death rate is accredited to more women getting mammograms, better evaluation processes, and more potent secondary treatments.

Thus if the majority of diagnosed breast cancer cases are discovered during the preliminary stages, what effect does that have on patients and what are the best treatment courses?

The Early Stages of Breast Cancer

Earlier breast cancer stages are called TNM stages 1, 2 and 3a. This scoring system approximates how far the carcinoma has advanced. It’s also based on whether any present tumors are operable.

The majority of early breast cancer cases are cured through either surgery, radiation therapy, systemic therapy or a combination of the three, resulting in a much greater survival rate.

Typical Treatment Response

Treatment response typically depends on lymph node involvement, the grade and size of tumors, estrogen and progesterone receptors, the status of biologic markers such as HER2/neu and the patient’s age.

Lymph Node Indicators

One of the most effective prognostic indicators for breast cancer are lymph nodes. As the number of positive lymph nodes increases, survival rates decrease and relapse rates go on the uprise.

Commonly, patients with earlier stage breast cancer are classified into either those presenting negative nodes, 1 to 3 positive lymph nodes, 4 to 9 positive nodes, or 10 and more nodes.

The Size of Tumor

Tumor size is another indicator and can be especially useful for patients with negative lymph nodes. Essentially, if a patient has negative nodes and a tumor that is less than 1cm, the prognosis is very favorable.

The Grade of Tumor

As the grade of the tumor increases, so does the potential relapse rate. However, due to the unreliability of tumor data, most pathologists do not rely on this information for their prognosis.

Estrogen and Progesterone Receptors

Estrogen and progesterone receptors within the tumor is also used to prognosticate breast cancer during the earlier stages. Generally, those patients with a receptor-positive form of breast cancer tend to have a better prognosis and survival rate than those who don’t.

HER2/neu as an Indicator

HER2/neu is what’s called a marker – it’s a biological element typically present in the body or within the tumor in about 25% of all breast cancer cases. When HER2/neu levels are high, that usually translates to a more aggressive variety of breast cancer and a worse prognosis.

Age of the Patient

Concerning various breast cancer stages, normally older patients (over the age of 50) have a stronger prognosis than younger patients (under the age of 35).

Whenever a person begins to experience and recognize his or her own symptoms of cancer, the signs can definitely create a lump in the throat at just the thought of a malignancy diagnosis and then the likely ensuing cancer treatments. This concern is even intensified at the prospect of cancer in the bladder.

There are two primary bladder cancer symptoms – a drastic change in urination habits or patterns, and blood in the urine. Unfortunately, many instances of this potentially deadly disease are still unrecognized in people’s lives.

Every year, over 54,000 cases of bladder cancer are diagnosed in America. And annually, over 12,000 people die from it. While the five-year survival rate is doing well at over 80%, that number could be higher if more instances of the disease were noticed and addressed early.

This is why understanding and detecting bladder cancer symptoms is so critical. To learn more about the different symptoms associated with the disease, along with possible risk factors – keep reading.

Evidences and Signs Associated with Bladder Cancer

Blood in the Urine: Blood in the urine is the single more important sign of bladder cancer. This symptom can also be associated with other diseases such as kidney cancer or gall stones, but is most common in bladder cancer.

Change in Urination Habits: Patients often complain of feeling an almost constant need to urinate, an urgency that’s accompanied by frequent urination. This can be a sign of bladder cancer, along with urinary incontinence.

Risk Factors for Bladder Cancer

Smoking: Smokers are more than twice as likely to develop bladder cancer than nonsmokers. Smoking causes about half of the deaths from bladder cancer among men and over 30% of bladder cancer deaths among women.

The carcinogens in cigarettes make their way into the blood stream and finally through the bladder and into the urine, which is why they’re such a major cause of bladder cancer.

Occupational Exposure: Industrial chemicals known as aromatic amines, like beta-napthylamine and benzidine which are sometimes used in the dye industry, can be a contributing factor for bladder cancer.

Other organic chemicals, like those used in rubber plants, leather manufacturers, fabrics and textiles and printing firms, are also a higher risk factor for the disease.

Race: Bladder cancer is typically more common in Caucasians than other races.

Age: The risk for developing bladder cancer increases with age. The average age for those diagnosed with the disease is around 68 years. Meanwhile, less than 1% of bladder cancer patients are age 39 and under.

Chronic Bladder Problems: Patients who have a long-term history of kidney stones, urinary infections, bladder stones or other forms of chronic bladder irritation may be at an increased risk for developing bladder cancer.

If you have been exposed to or belong to any of the above risk factors or categories, it’s critical that you understand and watch for bladder cancer symptoms like blood in the urine or sudden changes in your urination habits.

The prospect of facing a cancer diagnosis after agonizing over the recognition of disconcerting symptoms is troubling enough for anyone. But when it’s your own child dealing with similar concerns and the weighty decisions associated with potential cancer treatments, this is harder still. And unfortunately, malignancies among children are not so uncommon.

Childhood osteosarcoma is a rare cancer, though the 6th most common type of cancer in children aged 14 and under. The disease is the most frequented form of malignant bone cancer and affects approximately 900 people every year, 400 of whom are children.

What Leads to Osteosarcoma

Unfortunately, the causes behind osteosarcoma are not known. Theories exist about environmental triggers such as fluoride in drinking water or exposure to radium.

Symptoms Associated with Osteosarcoma

The first complaint or symptom that most patients experience is pain at the tumor location – typically this discomfort is more severe at night. Large tumors can often look like swelling. Another feature is that the bone affected by the cancer is frequently weaker and more susceptible to fracture.

Over 50% of all cases of childhood osteosarcoma occur around the knee area.

Risk Factors Associated with Osteosarcoma

Age

The risk of osteosarcoma is highest during the teenage “growth spurt” period. Since children with osteosarcoma are often tall for their age, some researchers believe there may be relationship between rapid bone growth and the risk for developing the disease.

Gender of the Patient

Osteosarcoma typically occurs in males and is seen twice as frequently as in young women.

Radiation

If a patient has been subjected to radiation treatment for other cancers or conditions, they will have a higher risk of contracting the disease.

Other Bone Diseases

Patients who have suffered from other bone diseases, like Paget’s disease of the bone, have an increased risk of being diagnosed with osteosarcoma. Typically though, this occurs in adults and is rare with children.

Genetics

Children with inherited and rare cancer syndromes, like retinoblastoma, are more prone to developing childhood osteosarcoma.

Types of Osteosarcoma

There are three sub-types of osteosarcoma that can be recognized by how they appear on X-rays and under a microscope. Some of these sub-types have a better prognosis than others.

The sub-types are high grade, which is a conventional, small cell and high grade surface development of the disease; intermediate, which is periosteal; and low grade, which is parosteal and characterized by low grade intrasseous.

How Osteosarcoma is Treated

Osteosarcoma is occasionally treated with surgery – at which point the afflicted limb or a portion of the afflicted limb is amputated. Usually, the patient or parents of the patient choose to use the same surgeon for both the biopsy and the therapeutic surgery.

Patients or the parents of patients should consult with their surgeon about the best method and how best to remove the cancer while saving as much use of the affected arm or leg as possible.

Despite the prevalence of surgery, most cases of childhood osteosarcoma are treated with chemotherapy in conjunction with surgery. There are a variety of drugs used in osteosarcoma chemotherapy programs, with each dose determined by the individual patient and disease.

The world can look depressing and harsh at times. Although various features of life are extraordinary, there are of course a few that give grief and sorrow. I think we all have to accept the good with the bad. Let’s say we’ll never know how it is to live in a perfect world. Disease is unfortunately one aspect of life as we know it. There’s no getting around the desolation caused by cancer. Millions of individuals are affected with this disease and it’s in the gene pool unfortunately. Therefore, there’s no way to prevent cancer completely. You can try your best to live healthy and stay fit, but it won’t absolutely avoid the big C. One thing you can do is to get as much cancer information as possible. The more you know, the better off you are.

My uncle and his wife both died from cancer. They lived on a farm where pesticides continually infected their drinking water. We all know that this is not the first time this happened. I believe others have been affected in this very same way. It’s sad when I think about it, because the right cancer information could have disallowed this tragedy. Knowledge can really save your life. As far as my uncle and his wife were concerned, they simply found out too late.

They should have know they were in danger. Fields around their house were routinely sprayed with chemicals and they drank water from their well. Not city water. It baffles me to this day. In the 1990s, this sort of cancer information was available. They just had to look at their condition. Something that’s nearly impossible not to do these days.
