If I'm diagnosed with one cancer, am I likely to get another?
cancer diagnosis is life-changing and can cause a range of concerns about ongoing health. Fear of cancer returning is one of the top health concerns. And managing this fear is an important part of cancer treatment.

Over time, these cancer cells can grow again and may start to cause symptoms.

Actor Hugh Jackman has gone public about his multiple diagnoses of basal cell carcinoma (a type of skin cancer) over the past decade.
The exact reason why cancer returns differs depending on the cancer type and the treatment received. Research is ongoing to identify genes associated with cancers returning. This may eventually allow doctors to tailor treatments for high-risk people.
What are the chances of cancer returning?
The risk of cancer returning differs between cancers, and between sub-types of the same cancer.
New screening and treatment options have seen reductions in recurrence rates for many types of cancer. For example, between 2004 and 2019, the risk of colon cancer recurring dropped by 31-68 per cent. It is important to remember that only someone's treatment team can assess
