Visible changes in the body

Some signs are more concrete and visible, but are often attributed to a simple temporary imbalance.

Rectal bleeding or blood in the stool: a warning sign of colorectal cancer.

Swelling in the neck, armpits, or groin: The lymph nodes may indicate a dysfunction of the lymphatic system.

Abnormal bruising or bleeding: Sometimes due to a low platelet count in certain blood cancers.

Persistent bloating: Particularly in women, this can indicate ovarian cancer.

Unexplained weight loss: Often linked to digestive or liver cancer.

Pain not to be ignored

Pain is a powerful body language. But when it persists without any apparent cause, it deserves special attention.

Back pain or pain in the right flank: Possible signs of liver cancer or breast cancer metastasis.

Pelvic pain: a common sign of ovarian cancer or an enlarged spleen in certain leukemias.

Recurrent stomach aches: persistent abdominal pain may be a sign of colorectal cancer.

Chronic cough or chest pain: when these last more than three weeks, they may indicate lung cancer.
