Why cancer is referred a killing disease?
Quite a few cancers can be cured these days. 7 out of 10 children are cured of cancer. Testicular cancer, Hodgkin's disease, and many cases of leukaemia can all be cured in adults with chemotherapy. Most skin cancers are cured with surgery. And many cases of thyroid cancer and cancer of the larynx (voicebox) are cured with radiotherapy.Many other types of cancer are also cured if they are found early enough - 3/4 of breast cancers found at stage one for example. Of course, there is still a long way to go. Particularly with some of the commonest types of cancer - lung, breast, bowel and prostate for example.
Difficulties in dealing with cancers
· Are caused by different things, so no one strategy can prevent them
· Respond to different treatments so no one treatment can cure them
There is much research going on in all types of cancer to try and find a cure. Biological therapies such as cancer vaccines, monoclonal antibodies and gene therapies are all active areas of research. There is also research into how cancers grow their own blood supplies. Researchers are beginning to test 'anti-angiogenic' drugs that may be able to stop that happening and so stop cancers from growing. Of course you still have to find them early enough for this to be a cure. But there is hope that this treatment may also stop cancer secondaries from developing. And cancer researchers work on developing new and more effective chemotherapy drugs all the time. Work goes on into refining and improving the treatment of different types of cancer. It is an approach that has come up with the treatments and cures we already have. And we hope will come up with more. Research also goes on into cost effective ways of screening for the different common cancers so that they can be diagnosed early enough for cure to be achievable.
Radio therapy plays a very active role in treating cancer.Radiotherapy is commonly performed using cobalt. The therapy aims in the destruction of cancer cells.
Cured patients do have cancer cells in them,but the treatment aims completely in bringing down the cancer cell concentrate rather than completely eliminating them.
