According to a new study, a blood test might be able to detect skin cancer in its early stages. This first of its kind melanoma blood test could save the millions of peoples’ lives. 

Scientists at Edith Cowen University in Australia said, "This new blood test will prove to be a strong weapon for doctors. It will be easy to catch melanoma.”

The lead author of the study said that if cancer spreads in the body, the survival rates fall to a 50 per cent. "This is what makes the blood test so exciting as a potential screening tool because it can pick up melanoma in its very early stages when it still treatable,” said the chief researcher of the study, Pauline Zaenker. 

So far, melanoma could be caught by a visual scan, which is a costly technique. For this research, scientists took blood samples of 105 people, who had melanoma and 104 healthy people. The result was positive in about 81.5 % of the total cases  

During the trial, this blood test proved right in 81.5 per cent of cases.

How Does Skin Cancer Spread?

The body is made up of millions of living cells. Usually, the body cells grow, and new cells are born, then the old cells die. This sequence goes on. Healthy cells proliferate in the early years of any person's life. After this, most new cells are ready to replace waste cells or repair damaged cells when it comes to puberty.

Skin cancer is caused by the rise of abnormal cells and it is of several types. The growth of cancer cells is very different from healthy cells. Cancer cells continue to grow instead of dying, and new cells stop growing.

Normal cells become transformed into cancer cells after DNA is damaged. When the DNA of a normal cell gets damaged, then that cell can be treated. However, damaged DNA cannot be repaired in cancer cells.

If any stains or spots on your body are itchy and blood is released, then you may have melanoma cancer. You must visit a doctor as soon as possible for its treatment.
