#7:. Changes in your mouth
If you smoke, chew, dip or spit tobacco, you need to pay close attention to changes inside your mouth. White patches inside your mouth or white patches on your tongue may be pre-cáncers.
Left untreated, these areas can turn into oral cancer. Sores, unexplained bleeding, numbness or tenderness in the area around your mouth – like your tongue, lips and cheeks – should tell you that it’s time for a check-up.
#8:. Unexplained weight loss
Are you dropping pounds without changing your diet or exercise habits? Call your doctor – even if you think they’re pounds you need to lose.
Losing ten or more pounds for no known reason can be a sign of pancreatic, stomach, esophageal or lung cancer.
