Does a rectal mass always mean cancer?

No, a rectal mass does not always mean cancer. While it can be a sign of malignancy, there are various non-cancerous conditions that can also cause rectal masses, such as hemorrhoids, abscesses, or benign tumors. A thorough evaluation, including imaging and possibly a biopsy, is necessary to determine the nature of the mass. It's important to consult a healthcare professional for an accurate diagnosis and appropriate management.
