How Might Psoriasis Increase Cancer Risk
Although this study does not specifically examine the reasons why people with psoriasis may be more likely to develop cancer, we can offer a few possible explanations. Psoriasis is an inflammatory condition involving overactive immune cells in the body. We know that other chronic inflammatory diseases, such as Crohns disease, are also associated with increased risk of developing cancers.
Many patients with psoriasis also have metabolic syndrome, tobacco use disorder, and increased alcohol use. Some of these conditions have also been associated with increased risk of cancer. This study does not go into detail about the extent to which these comorbidities may influence the increased risk of cancer in psoriasis patients.
People with severe psoriasis often do not get enough relief with topical therapies , such as topical corticosteroids and vitamin D analogues. They may then be started on medications that target specific immune cells and proteins. Some of these medications increase the risk of infections. Previous studies have found little to no increased risk of cancer in patients receiving these therapies. Other treatments, such as phototherapy , are known to increase risk of developing skin cancers.
Sneaky Psoriasis Sign #: Hand Or Foot Blisters
Raised red patches on the palms or soles are common with psoriasis, but an unlucky few develop deep blisters or pustules within these patches, says Dr. Katta. This is known as palmoplantar pustular psoriasis.
Smokers are at higher risk for this type, because nicotine can cause inflammation in the sweat glands of the hands and feet.
Protection Of Study Subjects
This study was developed in accordance with the STROBE guidelines and was approved by the institutional review board of the University of Pennsylvania and by the Scientific Review Committee of CSD Medical Research, United Kingdom. This study was a population-based study using data already collected for these purposes. Data were collected by a third party and deidentified before they were made available for research purposes. Because our study analyzed data already collected for these purposes, patient consent was not required.

Treatments Your Physician May Prescribe
There are many prescription-strength treatments that are helpful at controlling psoriasis. For mild or moderate cases, medicines applied directly to the skin may be prescribed:
- The mainstay of therapy for psoriasis is topical steroids, either in creams or ointment form. Higher-potency topical steroids are used for the body or scalp, and lower-potency topical steroids are best for the face and skinfold areas. Steroid solutions or liquids can be used on the scalp. Use should be limited to 14 weeks at a time because long-term use of steroids can lead to stretch marks and thinning of the skin.
- Calcipotriene is a vitamin D derivative cream that works as well as steroids, and it is even more effective when combined with topical steroids.
- Tazarotene is a vitamin A-based cream that may be prescribed. Women of childbearing age should be counseled to avoid pregnancy while using tazarotene because this treatment may cause birth defects.
- Topical immunosuppressants such as tacrolimus and pimecrolimus may also be used, but they can cause skin burning and itching and are expensive. These treatments may possibly increase your risk for skin cancer and lymphoma.
- Coal tar-based therapies and anthralin creams are sometimes used, but they are used less frequently than other treatments because they have an odor, cause skin irritation, and can stain clothing and because neither is any more effective than calcipotriene.

Signs And Symptoms Of Psoriasis
Psoriasis is a chronic skin condition that develops as the result of an overactive immune system. Normally, T-cells in the immune system function by attacking bacteria and viruses that lead to infection and harm the body. If you have psoriasis, T-cells mistakenly begin attacking healthy skin cells. This causes the life cycle of skin cell production to speed up and generate a surplus of new skin cells in a matter of days. The new cells build up on the surface of skin and form thick patches and scales that can be itchy, painful, or burning.
The most common symptom is the appearance of well-defined, raised red patches of skin covered with silvery scales. These thick skin lesions typically appear on knees, elbows, scalp, trunk, buttocks, and nails. However, the disorder can affect any area of skin on the body, including the genital region.
Under the broad name psoriasis, there are many different types:
- Plaque psoriasis is the most well-known form the skin condition takes. It is characterized by thick, raised red plaques that develop on the scalp, elbows, knees, and/or trunk. The plaques are often covered by dry, itchy silver-white scales.
- Nail psoriasis causes changes to the nails. Both fingernails and toenails can develop pitting, discolorations, and crumbling. Due to the build-up of skin cells under the nail, one or more nails can lift and become detached.

Psoriasis And Cancer: Is There A Link
New data adds to the evidence for a link between psoriasis and certain cancers, including skin cancer.
The association of psoriasis with several common comorbidities, including heart disease and metabolic syndrome, has now been firmly established. Less clear has been an association of psoriasis with risk for cancers, including skin cancers. One study published online in JAAD found that patients with psoriasis have an increased risk of mortality and showed that the risk is mediated, at least in part, by an increased prevalence of cardiovascular, infectious, and neoplastic disorders.1 A 2013 meta-analysis of epidemiological data identified an increased risk of squamous cell carcinoma and basal cell carcinoma in patients with psoriasis but did not identify increased melanoma risk.2

Is Bowen’s Disease Serious
Bowen’s disease itself is not usually serious. It tends to grow very slowly over months or years, and there are several very effective treatments for it.
The concern is that Bowen’s disease can eventually develop into a different type of skin cancer called squamous cell skin cancer if it’s left undiagnosed or neglected.
It’s estimated this happens in up to 1 in 20 to 1 in 30 people with untreated Bowen’s disease.
Squamous cell skin cancer is often treatable, but it can spread deeper into the body and is sometimes very serious.
Exposure To Certain Chemicals
Being exposed to large amounts of arsenic increases the risk of developing skin cancer. Arsenic is an element found naturally in well water in some areas. Its also used in making some pesticides and in some other industries.
Workers exposed to coal tar, paraffin, and certain types of petroleum products may also have an increased risk of skin cancer.

Do Some People Have A Higher Risk Of Getting Basal Cell Carcinoma
Yes. The main risk factor for getting this skin cancer is:
UV-damaged skin caused by the sun or tanning beds. Each time you go outdoors without protecting your skin from the sun or use a tanning bed, you increase your risk of getting skin cancer.
There are other risk factors for BCC, which include:
Color of your skin, hair, and eyes. This skin cancer develops in skin damaged by UV light, and skin is more easily damaged by UV light if you have one or more of the following:
- Skin that burns easily and rarely tans
- Sun-sensitive skin that freckles easily
- Naturally blonde or red hair
- Blue or green eyes
Sunburns. If youve had sunburns, especially blistering ones in your youth, you have a higher risk of developing this skin cancer.
Where you live. Living in an area that gets intense sunlight year-round, such as Florida or California, increases your risk of getting skin cancer. People who live at a high altitude also have an increased risk.
Previous skin cancer. If youve had any type of skin cancer, you have a greater risk of getting another one.
Weakened immune system. Anything that weakens your immune system increases your risk of getting this skin cancer. In fact, BCC is one of the cancers most likely to develop when the immune system weakens.If you received an organ transplant, the medication you take to prevent your body from rejecting the organ suppresses your immune system. This increases your risk of developing basal cell skin cancer greatly.
The Link Between Psoriasis And Cancer Isn’t Clear Yet But It Could Be Due To Inflammation
While it’s clear there is a link between psoriasis and cancer, researchers are still trying to determine the specific reason. According to , MD, a board-certified dermatologist with expertise in psoriasis, there are a few theories as to why psoriasis may increase someone’s risk of several types of cancer. One of the most prominent is that psoriasis heightens the level of inflammation in your body long term, and chronic inflammation has been linked to cancer.
“The thing to know is that psoriasis is not just a skin disease, it’s a systemic disease that affects the body inside and out,” Mikhail explains. “Also the skin is a marker for the level of inflammationthe more severe the skin disease, the more inflammation is circulating in the body.” And for more concerning health connections, If You Notice This on Your Hands, Get Your Liver Checked, Doctors Say.

How Skin Conditions Can Affect Skin Cancer Detection And Treatment
Millions of Americans are affected by skin cancer, but millions more are battling skin conditions like rosacea, eczema, psoriasis and melasma. Although bothersome, these conditions are usually harmless and manageable through ongoing treatment.
In dealing with my own bout of melasma, I got to thinking can these skin problems make it harder to spot a potential skin cancer? Can a dermatologist treat a patients condition and skin cancer simultaneously? I asked James Sandwich, MD, MPH a board-certified dermatologist practicing in Fayetteville, Georgia, to break down these conditions for us and how they impact skin cancer diagnosis and treatment.

A Patchy Red Rash That Can Turn Scaly: Lymphoma
Mycosis fungoides is a common rash in patients diagnosed with lymphoma.
Lymphoma is a cancer of the lymphatic system – the network of tissues and organs in our body that work to rid us of toxins.
It can be particularly dangerous because the cancerous cells can travel through the body in the bloodstream.
The cancer cells can then grow in several places at once, affecting multiple parts of the body.
A person with lymphoma may develop mycosis fungoides, a rash that is caused when the blood travels to the upper layer of the skin.
In its early stages it may appear as a patchy red rash but as it progresses it tends to become scaly.
It may be itchy and look similar to eczema.
Red Pinpricks With Flu
A red pinprick rash under the skin can signal meningitis, a sometimes fatal condition.
The symptoms of meningitis mimic the flu , and the rash may not always occur early on.
It starts as small, red pinpricks before spreading quickly and turning into red or purple blotches, the NHS says.
You can check if you or your child has it by pressing a glass against the rash – if it does not fade on pressure, then it is caused by meningitis.
It can be a sign of sepsis caused by meningitis and you should call 999 straight away.
All parents are told to vaccinate their babies against meningitis very early on.

How Can Uv Light Cause Skin Cancer
Every time UV light hits our skin, it can damage some of the DNA inside our skins cells. The body tries to repair this damage.
As UV light from the sun, indoor tanning equipment, or both, continues to hit our skin, the damage builds up. Eventually, it becomes too much for the body to repair. When the body cannot repair the damage, changes called mutations develop. When the mutations build up in the skin, we get skin cancer.
The type of skin cancer we get depends on where the mutations develop in the skin. Basal cells are found deep inside the first layer of our skin, so we get basal cell carcinoma when mutations develop inside these cells.
