Does Skin Cancer Discolor Upon Pressure- Unveiling the Mystery Behind ‘Blanching’ Lesions

Does skin cancer blanch when pressed? This is a question that often comes to mind when individuals suspect they may have a mole or lesion that could be cancerous. The concept of skin cancer blanching, or changing color when pressed, is a common myth that has been circulating for years. In this article, we will explore the truth behind this myth and provide valuable information on identifying and treating skin cancer.

Skin cancer is a serious condition that affects millions of people worldwide. It is primarily caused by overexposure to ultraviolet (UV) radiation from the sun or artificial sources. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Melanoma is the most dangerous form and can spread to other parts of the body if not detected and treated early.

The myth that skin cancer blanches when pressed is based on the idea that cancerous lesions have a different blood supply than healthy skin, causing them to lighten in color when pressure is applied. However, this is not true. In fact, pressing on a suspected skin cancer lesion will not cause it to change color. This is because the blood supply to cancerous cells is similar to that of healthy cells.

So, how can you tell if a mole or lesion is cancerous? The American Academy of Dermatology has developed the ABCDE rule to help identify potential melanomas:

1. Asymmetry: One half of the mole or lesion may look different from the other half.
2. Border: The edges of the mole or lesion may be irregular, scalloped, or poorly defined.
3. Color: The mole or lesion may have different shades of brown, black, red, white, or blue.
4. Diameter: The mole or lesion may be larger than the size of a pencil eraser (6mm or 1/4 inch).
5. Evolving: The mole or lesion may change in size, shape, color, or texture over time.

If you notice any of these changes in a mole or lesion, it is crucial to consult a dermatologist for a professional evaluation. Early detection and treatment of skin cancer can significantly improve the chances of a successful outcome.

In conclusion, the myth that skin cancer blanches when pressed is not accurate. Instead, it is important to be aware of the ABCDE rule and monitor any changes in your skin. If you have any concerns about a mole or lesion, don’t hesitate to seek medical advice. Early detection and treatment are key to preventing the spread of skin cancer and ensuring the best possible outcome.
