Screening is the process of looking for cancer before a person shows any symptoms. If the screening results turn out to be abnormal, you will require further test and find out if you have cancer. These tests will be called diagnostic tests.
Different types of cancer will require different types of tests. Screening tests are done because they are helpful in detecting cancer and decrease the chances of dying from it.
If you spot any signs or worrisome changes, you should immediately report it to your doctor. Regular skin checkups will be essential for people who have already undergone skin cancer treatments. If an area of your skin is seen to be abnormal, a biopsy will be required. Your doctor will remove a tissue sample with a local excision upon suspicion. A pathologist will closely observe the tissue for cancer cells. Sometimes it can be hard to tell if a skin growth is not cancer (benign) or cancer (malignant). In some instances, you will need the biopsy sample to be checked by another pathologist.
Most of the melanomas that appear on the skin can be seen by the naked eye. Usually, melanomas will grow under the top layer of the skin called the epidermis for a long time, but do not grow into deeper layers of the skin known as the dermis. This will allow for skin cancer to be found at an early stage.
Being exposed to UV radiation can increase the risk of skin cancer. Anything that can increase the risk of a disease is called a risk factor, but it does not mean you will get cancer. Having skin that is sensitive to UV radiation and being exposed to UV radiation can be considered as risk factors for skin cancer. UV radiation is rays that are invisible and emitted from the sun. Tanning beds and sunlamps will also emit UV radiation.
