3. Persistent Pain
Chronic pain that lingers without an obvious cause should be taken seriously. For example:
Back pain can signal bone or ovarian cancer.
Headaches that don’t respond to treatment may relate to brain tumors.
4. Unusual Lumps or Swellings
A new lump under the skin, in the breast, neck, groin, or armpits can be one of the earliest symptoms of abnormal cell growth. Always have persistent lumps checked by a doctor.
5. Skin Changes
Your skin can reflect what’s happening inside your body. Watch out for:
Darkening, yellowing, or redness of the skin
