Advanced cancer can heal itself.

Cancer can be self-healing completely.

The immune system of the human body has a strong ability to identify and eliminate abnormal cells. In some cases, due to unknown factors, the immune system is highly activated to effectively identify and attack cancer cells, making them gradually regress. For example, there may be some special immune cell subsets that are stimulated, or the body produces specific immune responses against cancer cells, thus achieving effective control or even elimination of tumors. Cancer cells themselves may undergo specific changes, such as genetic mutations or phenotypic transformations, that make them less capable of malignant proliferation and invasion, or become more sensitive to the microenvironment of the body, making them more susceptible to inhibition or elimination. This change in biological characteristics may occur spontaneously or may be influenced by external factors.

It should be clear that advanced cancer self-healing is still a rare event and cannot be regarded as a universal phenomenon or a substitute for regular treatment.
