Warning: You may have cancer even if you don't feel any pain or itch

Painless hematuria

Hematuria without abdominal pain is an early symptom of kidney cancer and bladder cancer. If blood in the urine is accompanied by abdominal pain, it may be urinary stones. Therefore, for the same hematuria, the difference between benign and malignant diseases mainly depends on the presence or absence of abdominal pain.

Painless breast lump

If the lump in the breast is painless, has an uneven surface when touched, has no obvious boundary with the surrounding normal tissue, and has a hard texture, it may be breast cancer.

Painless bloody nasal discharge

There are no symptoms such as headache, sore throat and nasal pain, but the nasal discharge often contains blood or blood clots, indicating the possibility of nasopharyngeal cancer.

Painless skin keratosis

It is common on the face and back of the hands. The skin presents as a circular rash-like change, which is locally flat or slightly raised, with brown or black scabs attached to the surface, but there is no pain. This is a precancerous manifestation of skin cancer.

Painless lymphadenopathy

If one or more of the lymph nodes in the groin, submandibular, armpits, neck, behind the occipital bone, around the ears, etc. are painless and enlarged and have a hard texture, you should be alert to chronic lymphocytic leukemia or lymphoma.

Painless gastric ulcer

Some elderly people suffering from gastric ulcers have no abdominal pain but suddenly develop black stools. After gastroscopy, it is found that the gastric ulcer has developed into gastric cancer. Therefore, when elderly people have physical examinations, they should try to do gastroscopy or upper gastrointestinal barium contrast radiography. If it is a painless gastric ulcer, early detection and early treatment can avoid cancer.
