Causal factorsThere are many different forms of cancer associated with every organ in the body from the extremely rare (heart cancer) to the four most common cancers (prostate, lung, breast (women) and colon). The causal factors in cancer vary wildly from genetic predisposition to environmental carcinogens with the exact make up of these carcinogens being highly disputed, but some are widely accepted as cancer causing. Radiation, environmental toxins, UV, obesity, viruses and chemical carcinogens such as benzene. Equally cancers can be very age specific such as retinoblastoma, which tends to affect the very young. Testicular cancer which tends to affect the 16-25 year old categories and prostate cancer which is a very common in the 60-80 year old category (fig 1 and 2) . . The Japanese populous have higher rates of colon and lung cancer compared to England in the ~ 30 – 70 age category but by 80 England has nearly caught the rate up.
Treatment of CancerThe treatment of cancer had developed greatly over the last few years. Firstly there are some screening techniques used to catch cancer before it has time to properly develop. These include mammography to screen for breast cancer as well as smear tests to screen for cervical cancer. In the majority of cancer cases however the patient detects the symptoms and will then relay these to a doctor who can make a diagnosis. The three main areas of cancer are surgery, chemotherapy and radiotheraphy. Depending on the type and severity of the cancer depend on which of these are used and often a combination of all of them are required.
