Psoriasis is a chronic skin condition that affects millions of people worldwide. It is characterized by red, itchy, and scaly patches on the skin.

While psoriasis is not a life-threatening disease, some studies suggest that it may increase the risk of certain types of cancer. In this article, we will explore the link between psoriasis and cancer and discuss which types of cancer are most commonly associated with psoriasis.

Psoriasis and Cancer: Understanding the Connection

Psoriasis is an autoimmune disease, which means that the immune system attacks healthy cells in the body. This attack causes inflammation and the development of plaques on the skin.

While the exact cause of psoriasis is unknown, researchers believe that genetics, environmental factors, and the immune system all play a role in its development.

Cancer, on the other hand, is a disease caused by the uncontrolled growth of abnormal cells in the body. Cancer cells can invade nearby tissues and organs and spread to other parts of the body through the bloodstream or lymphatic system.

While psoriasis and cancer are two very different diseases, some studies suggest that there may be a link between the two.

According to the American Academy of Dermatology, people with psoriasis may be at an increased risk of developing certain types of cancer.

Types of Cancer Associated with Psoriasis

While the link between psoriasis and cancer is not fully understood, some studies suggest that people with psoriasis may be at an increased risk of developing the following types of cancer:.

Skin Cancer (including Melanoma)

Studies have found that people with psoriasis may be at an increased risk of developing skin cancer, including melanoma. Melanoma is a type of skin cancer that develops in melanocytes, the cells that produce pigment in the skin.

People with psoriasis who receive phototherapy or other treatments that involve exposure to UV light may be at an even higher risk of developing skin cancer.

Lung Cancer

Some studies suggest that people with psoriasis may be at an increased risk of developing lung cancer. One study found that people with severe psoriasis are more likely to develop lung cancer than those with mild psoriasis or no psoriasis.

This increased risk may be due to the inflammation caused by psoriasis, which can damage the lungs and increase the risk of lung cancer.

Liver Cancer

Other studies have found that people with psoriasis may be at an increased risk of developing liver cancer.

The reason for this link is not fully understood, but researchers believe that chronic inflammation caused by psoriasis may increase the risk of liver disease, including cirrhosis and liver cancer.

Lymphoma

Lymphoma is a type of cancer that affects the lymphatic system, which is responsible for fighting infections and filtering toxins from the body.

Some studies have found that people with psoriasis may be at an increased risk of developing lymphoma, but the link between the two is not fully understood. Researchers believe that the inflammation caused by psoriasis may play a role in the development of lymphoma.

Colon Cancer

Studies have found that people with psoriasis may be at an increased risk of developing colon cancer.

The reason for this link is not fully understood, but researchers believe that inflammation caused by psoriasis may increase the risk of colon cancer by damaging the DNA in cells lining the colon.

Reducing the Risk of Cancer for People with Psoriasis

If you have psoriasis, there are several steps you can take to reduce your risk of developing cancer:.

Stay Sun-Safe

If you receive phototherapy or other treatments that involve exposure to UV light, it is important to protect your skin from the sun. Wear protective clothing, such as long-sleeved shirts and hats, and use sunscreen with an SPF of at least 30.

Quit Smoking

If you smoke, quitting is one of the best things you can do for your health. Smoking not only increases the risk of cancer but also worsens the symptoms of psoriasis.

Eat a Healthy Diet

Aim to eat a diet rich in fruits, vegetables, whole grains, and lean protein. These foods contain nutrients that can help support a healthy immune system and reduce inflammation.

Manage Stress

Stress can worsen the symptoms of psoriasis and may also increase the risk of cancer. Practice relaxation techniques such as yoga, meditation, or deep breathing to help manage stress.

Conclusion

Psoriasis and cancer are two very different diseases, but some studies suggest that there may be a link between the two.

People with psoriasis may be at an increased risk of developing certain types of cancer, including skin cancer, lung cancer, liver cancer, lymphoma, and colon cancer. While the exact cause of this link is not fully understood, researchers believe that chronic inflammation caused by psoriasis may play a role.

To reduce the risk of cancer, people with psoriasis should practice sun safety, quit smoking, eat a healthy diet, and manage stress.
