7- Changes in the appearance of skin moles
If there are changes in the sizes of moles then it would rarely cause pain or any other serious health issue. However, doctors recommend cancer screening when you notice a new mole or changes in the size and shape of the existing mole. Also, if you see the clear boundary of any mole becoming blurry day by day, then please consult a doctor.These changes may be a sign of skin cancer, which if detected early, is easy to cure.
8- Changes in nails
Unusual changes in the sizes and shapes of fingernails can indicate the occurrence of several cancerous conditions like lung cancer, liver cancer, skin cancer and kidney cancer. Although, these changes can also be because of some other issue, but do not take any significant change in your nails lightly as these changes can be a warning sign. If your nail color becomes white, then it may be the first sign of liver cancer. Black or brown spots under your nails may indicate skin cancer.
