How do people get cancer?

Cancer. Cant answer in this short space. Some is genetic, lifestyle, exposures - excess sunlight, noxious materials, excess radiation- too many ct scans, x-rays. One theory is we produce cancer cells waiting for chance to grow- xs radiation, viral triggers, but ultimately lifestyle. Think consulting good nutritionist, review diet, lifestyle. Many foods are cancer fighting, anti oxidants, exercise, sun pro.
Cancer Causes. Doctors often cannot explain why one person develops cancer and another does not. But research shows that certain risk factors increase the chance that a person will develop cancer. These are the most common risk factors for cancer: growing older, tobacco, sunlight, ionizing radiation, certain chemicals and other substances, some viruses and bacteria, certain hormones, family history of cancer, .
Multifactorial. It is believed that cancer comes about when the normal growth patterns of cells becomes abberant and there is thus rapid proliferation of the cells. This displaces the normal tissues. What triggers this uncontrolled growth is unknown. There are numerous associations that have been clearly shown to predispose one to cancer. For example, smoking, exposure to radiation, exposure to certain chemicals.

How do people get sarcoma cancer?

We don't really know. Most sarcomas are sporadic, and they don't (usually) run in families. Some very rare genetic disorders may predispose subjects to them. Other rare causes are radiation therapy use (in very few breast cancer survivors), exposure to an old contrast agent called thorotrast, chronic lymphedema, and HIV (kaposi sarcoma). Read more...
Usually random. Sarcomas are bone and soft tissue cancers. Generally, these occur because of random events in most patients. However things like radiation exposure can increase the risk of bone and soft tissue sarcomas particularly with higher dose radiation like used for treatment of other cancers. There are some genetic diseases like li-fraumeni that can result in getting a sarcoma and other cancers. Read more...

How do people get over cancer. I mean I still am bummed over factor why me? What made me had testicular cancer I don't do drugs or smoke, no risky sex

Time helps. There are different risk factors predisposing to cancer such as smoking for lung cancer, cryptoorchidism or undescended testis for teticular cancer. A family history of cancer increases the risk. However, all these factors maybe absent and you can still have cancer. You did not do anything to have cancer but it just happened. Hopefully, the cancer was completely removed by the surgery. Read more...

How do people get eye cancer?

Multiple steps. Any cancer, including eye cancer, is the result of multiple insults to the cells. Some of the insults may be inherited mutations, most are environmental injuries. The cumulative effect is to increase the proliferation of cells, non-response to usual regulation, ability to invade and metastasize. Read more...
