Question: What is the 5 year survival rate for cancer ? http://www.cancer.org/docroot/CRI/content/CRI_2_4_3X_How_is_Anal_Cancer_staged_47.asp
If you live cancer free for 5 years then
are your odds much higher for survival?
Answer: Why do you keep posting a link about anal cancer whatever the content of your question?
With some types of cancer, if the cancer hasn't returned within 5 years, it's not going to. Cervical cancer is an example.
With some other types of cancer this is not the case and cancer can return at any time, even years after diagnosis and treatment. Breast cancer is an example.
However, with breast cancer recurrences are most likely to happen within the first two years, and after 5 years the risk is considerably reduced and continues to decline with each passing year.
