Medical experts are emphasizing the difficulty of distinguishing cancer symptoms from common, benign ailments to encourage early detection.

Regarding anal cancer, specialists note that symptoms such as rectal bleeding, pain, itching, or discharge are frequently mistaken for hemorrhoids or anal fissures. Research indicates that approximately 90 percent of cases are linked to human papillomavirus (HPV) infection. Risk factors include tobacco use, immunosuppression, and certain sexual histories. Experts have added that sudden lumps near the anus and changes in bowel habits should also be monitored.

In addition to anal cancer, health experts have raised concerns regarding prostate cancer. Men often dismiss urinary changes—including frequent urination or a weak stream—as normal signs of aging or benign prostatic hyperplasia (BPH). While urinary infections or diabetes can cause similar symptoms, medical professionals warn that persistent changes, or the presence of blood in the urine and semen, require investigation. Because early-stage prostate cancer often presents no clear symptoms, experts emphasize that persistent pelvic, hip, or lower back pain should also be evaluated by a doctor.
