If you have cancer such as breast cancer, prostate cancer, cervical cancer or lung cancer, you will work with a local oncologist in addition to your local family physician. Local oncologists are medical doctors who are specially educated and trained in oncology, which involves diagnosing and treating cancer. The type of local oncologist you will see depends on the type of cancer you or your family member has. For example, a child with cancer will be referred to see a pediatric oncologist by their local family physician. If you have bone cancer, you may see an orthopedic oncologist for treatment or a local orthopedic surgeon for orthopedic surgery. If you have ovarian cancer, you may see a gynecologic oncologist. Depending on the type of cancer you have, you may undergo surgery to remove a tumour, radiation therapy or chemotherapy. Radiation therapy uses high-energy x-rays to destroy cancer cells, while chemotherapy uses chemicals to destroy them. Your local family physician can be a good resource on the lifestyle changes you can make to prevent certain types of cancer, including quitting smoking, eliminating or reducing alcohol consumption and reducing saturated fats and sodium.
