Watchful waiting: not all cancers need to be treated immediately
They emphasize the importance of a more conservative approach, which allows doctors to avoid unnecessary aggressive treatments
Immediate treatment for certain types of cancer can often be harmful. Medical experts, such as Dr. Marc Siegel, emphasize the importance of a more conservative approach, known as “watchful waiting.” This method allows doctors to avoid unnecessary aggressive treatments.
“The fact that so many types of cancer never kill a person doesn't justify not knowing, because there is still plenty of room for 'watchful waiting,' as well as interventions that can improve quality of life even if they don't prolong it,” the doctor told Fox News Digital.
He also clarifies that “the fact that cancers are appearing at a younger age justifies a greater number of screening tests, not the other way around.”
Types of cancer to watch for
Thus, some types of cancer that may not require treatment, according to research and doctors' guidelines, are presented:
Low-risk prostate cancer. Dr. Sanoj Punnen indicates that in cases of low-risk prostate cancer (Gleason score 6), observation is preferable to immediate treatment. This is because low-grade tumors present a limited risk.
Ductal carcinoma in situ (DCIS). DCIS, a non-invasive form of breast cancer, may be best managed with active surveillance. A study from the Dana-Farber Cancer Institute suggests that this approach produces similar quality-of-life outcomes compared with surgery.
Indolent lymphomas. Slow-growing lymphomas, such as follicular lymphoma, require less intervention in early stages. Active surveillance is recommended until symptoms appear.
Chronic lymphocytic leukemia. Research suggests that in asymptomatic chronic lymphocytic leukemia, waiting may be more beneficial than early treatment, without improving survival rates.
Patient Considerations
The decision to adopt an active surveillance approach should be discussed between the patient and the oncologist.
Individualizing treatment is crucial, considering the nature of the cancer and the patient's overall health.
Cancer Classification
Cancers classified as low-risk and suitable for active surveillance are typically prostate cancers with indolent characteristics that do not require immediate treatment, according to guidelines such as the NCCN and AUA. This strategy aims to avoid overdiagnosis and unnecessary side effects through close monitoring.
