How is it treated?
There are five main types of treatment for cancer and these are described below:-
Active surveillance (or watchful waiting)
Some types of cancer grow very slowly and may cause no problems for many years. In this situation you may not need to have any treatment for some time, but your doctor will monitor you closely so that if the cancer does start to grow you can be given treatment at that time.
Surgery
An operation is done to remove the tumour. Surgery is often used if the cancer is only in one area of the body and has not spread. It may be used to remove lymph nodes if these are also affected by the cancer. It can sometimes be used to remove a cancer that has spread to another area of the body, but this is not common. The type of operation will depend on the area of the body affected by the cancer, and on the size and position of the tumour.
Radiotherapy
This is the use of high energy x-rays to destroy cancer cells, but cause as little harm as possible to normal cells. The radiotherapy is aimed at the affected area of the body and is very carefully planned. It can cause side effects and the most common is tiredness. The side effects will depend on the part of the body that is being treated.
Chemotherapy
Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells. There are more than 50 different chemotherapy drugs. Some are given as tablets or capsules but most are given by drip (infusion) into a vein. The drugs go into the bloodstream and travel throughout the body to treat the cancer cells wherever they are. Sometimes just one chemotherapy drug is used, but often a combination of two, three or more drugs is given.
Chemotherapy can cause side effects. The side effects will depend on which drug (or combination of drugs) is used. There are now very good ways of preventing or reducing the side effects of chemotherapy.
Hormonal therapy
Hormonal therapies work by altering the levels of particular hormones in the body. Some cancers depend on certain hormones in order to divide and grow. By altering the level of hormones in the body, or blocking the hormones from attaching to the cancer cells the cancer can be controlled.
Other treatments
Other treatments can be used to cure or control a cancer. These include chemicals which stimulate the body's immune system to attack the cancer cells. They are called biological therapies and include interferon and interleukin.
Monoclonal antibodies are drugs that can `recognise' and find specific cells in the body. These drugs can be designed to find a particular type of cancer cell, attach itself to them and destroy them. They can be used alone, or a radioactive molecule can be attached to a monoclonal antibody, which then delivers radiation directly to the cancer cells.
Research is trying to see whether vaccines can be given to treat a cancer that has come back or has spread. Vaccines may also be able to reduce the chance of a cancer coming back, but this type of research is in the very early stages.
Cancerbackup has information on all the cancer treatments mentioned above and also on cancer research trials.
