Cancer recurrence is a complex phenomenon that can occur for several reasons. After treatment, some cancer cells might not have been completely eradicated and can remain dormant in the body. Over time, these cells may become active again, leading to a cancer recurrence. This can happen in the same area where the cancer was originally treated, known as a local recurrence, or in a different part of the body, which is referred to as a secondary cancer or metastasis. The ability of cancer to evade the immune system, adapt to treatments, and develop resistance to therapies are also factors that can contribute to its return. Additionally, the genetic makeup of the individual and the specific characteristics of the cancer itself play a role in determining the likelihood of recurrence. read more >>
