4. Unusual lumps or swellings
A new lump under the skin, in the chest, neck, groin, or armpit, can be one of the first symptoms of abnormal cell growth. Always have persistent lumps examined by a doctor.
5. Skin changes
Your skin can reflect what is happening inside your body. Note:
Darkening, yellowing, or reddening of the skin
Wounds that do not heal
New or changing moles
These may be related to skin cancer or internal cancers.
6. Persistent cough or hoarseness
A cough that persists for longer than three weeks, especially if there is blood in it, may indicate lung or laryngeal cancer. Hoarseness that does not improve can also be a warning sign. Click through to the next page.
