Your skin can reflect what’s happening inside your body. Watch out for:
Darkening, yellowing, or redness of the skin
Sores that don’t heal
New or changing moles
These may be linked to skin cancer or internal cancers.
6. Persistent Cough or Hoarseness
A cough lasting more than three weeks, especially with blood, could point to lung or throat cancer. Hoarseness that doesn’t improve may also be a warning sign.
7. Changes in Bowel or Bladder Habits
Sudden constipation, diarrhea, blood in the stool, or changes in urination frequency may signal colon, bladder, or prostate cancer.
