Cancer: Learning Health Online
Cancer has affected millions of lives. Almost everyone has a close friend or family member that has had a battle with cancer. Since cancer is so prominent, it is important that a person be able to understand exactly what cancer is, how it comes about, ways to prevent it and what the treatment options are for those that are doing battle with it. Patients, family members, caregivers and support persons are all in need of accurate and beneficial information that can help them navigate the confusing maze of medical terminology and treatment options.
What is Cancer?
Cancer is an abnormal growth of cells. The growth is abnormal because the cells develop at a much faster rate and in a different pattern than normal, non-cancerous cells. Because of the rapid growth rate, untreated cancer cells can divide from the main growth site and spread, or metastasize, to other areas of the body. The immune system’s reaction to these cells determines the level of progression of the cancer.

Signs and Symptoms
Some types of cancer have obvious signs and symptoms, while others may not present with any symptoms at all. As cancer progresses, symptoms are more likely to show up. The types of symptoms to watch for will vary depending on the type of cancer. Symptoms can include anything from pain to unexplained weight loss.

- Pancreatic Cancer Symptoms Cancer of the pancreas causes an unexplained weight loss and pain in the abdomen.
- Kidney Cancer Symptoms Kidney cancer often advances through the beginning stage with few signs or symptoms. Possible signs include pain, anemia and fatigue.
- Ovarian Cancer Backaches that will not go away, a feeling of being bloated and indigestion are some of the common symptoms noticed with ovarian cancer.
- Prostate Cancer Symptoms Symptoms of prostate cancer include a feeling of burning during urination, trouble fully emptying the bladder and blood in urine.
Various factors can contribute to cancer cell growth. Genetics are sometimes, but certainly not always, involved. Smoking, UV exposure and other carcinogens damage cells and increase the risks of getting cancer. Preventative steps include eating a healthy diet full of antioxidant containing fruits and vegetables. Avoiding carcinogens and toxins is also a good measure to take as it decreases exposure to free radicals.
- Cancer and its Causes From genetics to UV exposure, this page lists various factors that can increase the abnormal cell growth that occurs in cancer.
- The Effect of Genetics in Cancer Genetics are responsible for some types of cancer. Hereditary traits are passed through the genes and can have an effect on cell growth.

Treatment for cancer is dependent on not only the type of cancer, but also the progression of it. In most cases, cancer in early stages will be treated differently than that which has advanced and metastasized. Treatments range from chemotherapy to radiation to palliative care. The patient is the key decision maker when it comes to the treatment options.
