New Delhi: Our skin is a reflection of our health. Many times, any disturbance going on in our body is indicated through the changes seen on the skin. Especially in a serious disease like blood cancer, some special symptoms can emerge on the skin, which should not be ignored. Blood cancer can be treated better if identified on time. Let us know the main signs of blood cancer that appear on our skin.

Unnecessary injury marks or bleeding

If blue, purple, or black marks suddenly start appearing on the skin without any injury, then it should be taken seriously. In blood cancer, the number of platelets, which work to form blood clots, decreases.

When these platelets are low, small blood vessels can break, and due to bleeding, such marks start appearing under the skin. These marks are often painless and keep increasing.

Red, brown, or purple spots on the skin

Blood cancer can cause small red or purple spots on the skin. These spots are caused by bleeding under the skin and do not fade even after pressing. These symptoms are especially visible on the legs. These are also a sign of lack of platelets.

Feeling of constant itching

If there is constant itching on the skin without any rash or allergy, then this can also be a symptom of blood cancer. Especially in a disease like Hodgkin lymphoma, cancer cells release chemicals called cytokines in the body, which cause irritation and itching in the skin. This itching often occurs more in the legs, hands, and other parts of the body.

Yellowing of the skin

Yellowing of the skin and the white part of the eyes (as happens in jaundice) can also be a sign of blood cancer. This occurs when red blood cells are damaged due to cancer or the liver is affected, causing increased levels of bilirubin. This results in the skin turning yellow. It can also be a serious symptom of anemia.

Rashes or wounds on the skin

Red, pink, or purple rashes may appear on the skin in blood cancer. These rashes can be raised or flat. In some cases, cancer cells collect directly in the skin and form wound-like marks. These marks do not heal with normal creams or medicines and continue to grow over time.

These skin symptoms of blood cancer often appear in the early stages. If you see marks of injury, persistent itching, color change, or rashes on the skin without any reason, contact a doctor immediately. This serious disease can be controlled with timely examination and treatment. So do not ignore any unusual changes on your skin.
