Cancer is not contagious. However, some cancers are caused by viruses and bacteria e.g. Human Papillomavirus (cervical cancer), Hepatitis B and Hepatitis C (liver cancer), Epstein Barr virus (lymphomas, nasopharyngeal cancers and stomach cancer) or Helicobacter pylori bacteria (stomach cancer)
If no one in your family has ever suffered from cancer it does not guarantee that you will not get cancer. Only 5-10 % of the cancers are familial or hereditary. The rest are caused by genetic changes that occur throughout a person’s lifetime by chance, natural result of aging and exposure to environmental factors, such as tobacco, smoke and radiation.
Although having a family history of cancer increases your risk of developing the disease, it is not a definite predictor. Only about 5 to 10 % of cancers are caused by harmful mutations that are inherited from a person’s parents .
Cancer is not a death sentence. Advances in cancer detection and treatment have increased survival rates for most common types of cancer. In fact, many people with cancer survive five years or more after their initial diagnosis .
The cancer may not be painful in the early stages. However, as it grows and spreads to other parts it may become painful. In the majority of cases cancer pain can be successfully treated with medications and other pain management techniques .
There is no age limit for cancer treatment. Many elderly patients may respond as well to cancer treatment as younger patients. People with cancer should receive the treatment that is best suited to their condition, regardless of age .
Cancer treatments such as chemotherapy and radiation therapy are known to cause side effects that can be unpleasant and sometimes serious. However recent improvements have resulted in better tolerance to many chemotherapy drugs and radiation treatments. The adverse symptoms like severe nausea and vomiting, hair loss, and tissue damage are much less common these days; however, managing side effects remains an important part of cancer care. Your doctor along with a palliative or supportive care team, can help a person to manage and control side effects of treatment at any stage of illness [8,9].
Many cancer patients are treated on an outpatient basis or require short hospital stay only, and can often continue with their day-to-day activities. They can work part-time or full-time, care for their children, and attend social activities, even while undergoing cancer treatment .
According to most studies conducted so far, cell phones have not been found to be causative for cancer. Cancer is caused by genetic mutations, and cell phones emit a type of low-frequency energy that does not damage genes. However, whether cell phones and cell phone towers cause cancer still remains controversial .
Although some studies suggest that alternative or complementary therapies, including some herbs, may help patients cope with the side effects of cancer treatment, no herbal products have been scientifically proven to be effective in treatment of cancer .
