Difference between Blood Blister and Melanoma

Do you have an unusual-looking spot on your skin? While it could simply be a harmless blood blister, it is important to familiarize yourself with the symptoms of melanoma—the most serious form of skin cancer. Educating yourself and understanding the differences between a blood blister and melanoma can save your life or that of a loved one. In this blog post, we will explore the similarities and differences between these two conditions so you know when to consult a doctor right away.

What is Blood Blister?

  • Blood blisters, also known as hematomas, are those pesky red bumps that form on the skin and can be extremely uncomfortable. Blood blisters usually occur when the skin is rubbed too hard or trapped between two objects.
  • They happen when the blood vessels become trapped beneath the surface of the skin, causing an increase in pressure and a build-up of blood.
  • Blood blisters normally heal on their own but if nursing is necessary, it’s best to use warm compresses or bandages to draw out fluid from the blister and keep it from becoming contaminated or growing larger.

What is Melanoma?

  • Melanoma is a serious and potentially life-threatening form of skin cancer. Melanoma can develop anywhere on the body, although it’s most common in areas exposed to the sun. It occurs when pigment cells or melanocytes grow out of control and form a lump or tumor.
  • Melanomas often look like unusual moles, although they may also be flat, pale, or contain multiple colors. Melanoma is highly treatable if detected early; however, if it spreads to other areas of the body, it can be difficult to manage.
  • That’s why it is so important to schedule regular checkups with your doctor as well as do monthly self-exams to look for any suspicious moles or patches of skin that should be evaluated by a specialist. By staying alert and taking preventive steps, you can protect yourself against Melanoma.

Difference between Blood Blister and Melanoma

Blood Blister and Melanoma are two distinct medical conditions that can cause concern.

  • Blood Blisters often appear on the outermost layer of the skin due to a localized trauma, such as hitting your foot on the kitchen counter.
  • Blood vessels beneath the surface of the skin swell with blood and form a dome-shaped blister. Blood blisters are usually temporary and can heal rather quickly without treatment.
  • On the other hand, Melanoma is an aggressive form of skin cancer caused by extensive exposure to ultraviolet radiation or prolonged sunbathing.

This tumor is located in the epidermis layer of the skin, where pigment cells known as melanocytes are produced. Further testing may be required if a suspicious mark appears during an initial screening. If acknowledged early, signs of Melanoma can be successfully treated before spreading to other areas of the body.


If you have a growth or mole on your skin that is causing you concern, it is important to have it checked out by a dermatologist. Sometimes something may just look like a blood blister when it is actually melanoma. Other times, what appears to be melanoma may turn out to be a harmless cyst. A trained professional will be able to determine what the growth is and whether or not it needs to be removed. If you are ever unsure about a spot on your skin, err on the side of caution and make an appointment with a dermatologist.
