Visible Changes in the Body
Some signs are more noticeable but are often mistaken for temporary issues:
- Blood in the stool or rectum: May indicate colon cancer.
- Swelling in the neck, armpits, or groin: Enlarged lymph nodes may signal problems in the lymphatic system.
- Bruising or abnormal bleeding: Sometimes caused by low platelet counts in certain blood cancers.
- Persistent swelling: Especially in women, could indicate ovarian cancer.
- Unexplained weight loss: Often associated with digestive system or liver cancers.
Pains That Should Not Be Ignored

Pain is a powerful way your body communicates. Persistent pain without a clear cause deserves attention:
- Back or right-side pain: Could be a sign of liver cancer or metastatic breast cancer.
- Pelvic pain: Common in ovarian cancer or an enlarged spleen in some types of leukemia.
- Recurring abdominal pain: May indicate colon cancer.
- Chronic cough or chest pain: If it lasts more than three weeks, it could signal lung cancer.
