Can cancer go away on its own?

As an oncologist with extensive experience in cancer research and treatment, I can provide some insights into the question of whether cancer can go away on its own. While it is true that some cancers can become chronic and may appear to go away or remain stable while a person is undergoing treatment, it is important to understand that this does not mean the cancer has been cured. In the case of metastatic cancers, such as breast or prostate cancer, the cancer has already spread to other parts of the body. Treatment may control the disease, but it is not typically eradicated without medical intervention. There are very rare instances where a person's immune system might respond effectively to the cancer, leading to a spontaneous remission. However, these cases are exceptional and not the norm. It is crucial for individuals with cancer to seek medical treatment and follow their healthcare provider's recommendations. In summary, while there are anecdotal reports of cancers seemingly going away on their own, this is not a common occurrence and should not be relied upon as a treatment strategy. The best approach to dealing with cancer is through a combination of medical treatments aimed at controlling and, when possible, eliminating the disease.

Sometimes cancers that have spread or have come back in other parts of the body, like metastatic breast or prostate cancer, also become chronic cancers. The cancer may be controlled with treatment, meaning it might seem to go away or stay the same. The cancer may not grow or spread as long as you're getting treatment.
