Exploring the Link Between Psoriasis and Cancer: New Study Insights

Oct 01, 2023

Is psoriasis cancer? Psoriasis is not cancer. In contrast to cancer, psoriasis is caused by an overactive immune system and rapid skin cell turnover. The distinction in the underlying mechanisms of 'psoriasis vs. skin cancer' highlights the differences in their nature, even though both conditions involve abnormal cell growth.

Emerging Research: Psoriasis and Cancer Risk

Recent research suggests psoriasis may raise cancer risk. Researchers say psoriasis raises the risk of some cancers. Persistent psoriasis inflammation may cause cancer.

Lymphoma

Lymphoma is psoriasis-related. Lymphoma is an immune-boosting lymphatic tumor. Chronic inflammation and enhanced immunological activity in psoriasis patients may induce lymphoma, although how is uncertain.

Skin Cancer

When discussing 'psoriasis vs. skin cancer,' remember that psoriasis is not skin cancer. However, their relationship is unavoidable. Inflammation and fast skin cell turnover in psoriasis can promote squamous cell carcinoma and melanoma.

Malignancies

Psoriasis can cause lung, oral, and esophageal cancers. Psoriasis inflammation may promote organ cancer due to its systemic nature.

The Intersection of Psoriasis and Cancer

JAMA Dermatology's comprehensive review and meta-analysis revealed this noteworthy finding. Manchester University researchers examined 58 studies for this thorough investigation. The results showed that psoriasis patients had an 18% higher cancer risk than those without the inflammatory illness. Severe psoriasis increased this risk to 22%.

Investigating the Link: Why and How

Understanding how psoriasis increases cancer risk is essential for designing prevention methods. Psoriasis' persistent inflammation may explain the link. Chronic inflammation causes DNA damage, cellular proliferation, and angiogenesis, which fuel cancer.

Psoriasis' immune system dysregulation may also hinder the body's ability to recognize and eliminate precancerous and cancerous cells, increasing risk. Lifestyle factors and psoriasis comorbidities like obesity and smoking may potentially increase cancer risk.

The Immune System

The immune system plays a complex function in psoriasis and cancer. Psoriasis causes inflammation and rapid skin cell proliferation due to immune system overactivity. Chronic inflammation can damage DNA, induce angiogenesis, and decrease anti-tumor immune responses, making it a cancer risk factor.

Immune System Disorders

In psoriasis, immune cells mistakenly attack healthy skin cells. Dysregulation can also impair the body's capacity to recognize and clear aberrant, potentially malignant cells, increasing cancer risk.

Inflammation and Cancer

Chronic inflammation in psoriasis promotes tumor growth. Pro-inflammatory cytokines and growth factors can promote cell proliferation, suppress apoptosis, and cause genetic instability, which can lead to cancer.

Treatment Effects

Understanding the relationship between psoriasis and cancer affects treatment. Cancer risk requires careful assessment of treatment modalities, especially those that affect the immune system or create persistent immunosuppression.

Immunosuppressive Therapies

Many psoriasis treatments involve immunosuppressive therapies, which dampen the overactive immune response characteristic of the condition. However, these therapies can also reduce the body’s ability to fend off infections and detect abnormal cells, potentially heightening cancer risk.

Regular Monitoring and Screening

For individuals with psoriasis, regular monitoring and screening for cancer are paramount. Early cancer detection can significantly improve prognosis and treatment outcomes, making it crucial for psoriasis patients to undergo routine screenings, particularly for the types of cancer associated with the condition.

The Chronic Inflammation Theory

At the crux of the scientific discourse is the theory positing chronic inflammation, a hallmark of psoriasis, as a potential catalyst for cancer development. Trafford elucidates that the persistent inflammatory state endemic to psoriasis can foster an environment conducive to cancer development. Chronic inflammation has been implicated in a spectrum of malignancies, instigating cellular changes in DNA mutations and promoting angiogenesis, laying the groundwork for cancerous growth.

Implications of Psoriasis Treatments

Trafford underscores the potential role of psoriasis treatments in exacerbating cancer risk. While productive in managing psoriasis symptoms, therapeutic interventions such as phototherapy and immunosuppressants may inadvertently contribute to increased susceptibility to cancer. Phototherapy, for instance, entails exposure to ultraviolet light, which, although mitigating skin inflammation, can induce DNA damage, a precursor to cancer. Similarly, by dampening the immune response, immunosuppressants may compromise the body’s natural defense mechanisms against abnormal cell growth.

Lifestyle Factors: Smoking, Alcohol, and Obesity

Compounding the complexity of the psoriasis-cancer nexus are lifestyle factors prevalent among individuals with psoriasis. Trafford highlights that studies have consistently reported higher incidences of smoking, alcohol consumption, and obesity among psoriasis patients. These lifestyle factors are established carcinogens, accentuating this demographic's cancer risk.

A Balanced Approach to Risk Management

Given the intricate interplay of factors contributing to increased cancer risk in psoriasis patients, a balanced, holistic approach to risk management is paramount. Evangelos Kontopantelis, PhD, a professor at the University of Manchester and co-author of the study, offers pragmatic insights for individuals navigating life with psoriasis.

Assessing Individual Risk

Kontopantelis advocates for a measured response to the study’s findings, emphasizing the importance of contextualizing the increased risk within an individual’s baseline risk of developing cancer. He underscores that while the correlation between psoriasis and cancer is significant, it necessitates a nuanced understanding and personalized risk assessment.

Holistic Approach to Psoriasis Care

In light of the multifaceted nature of cancer risk, Kontopantelis champions a holistic approach to psoriasis care, encompassing medical interventions and lifestyle modifications. He encourages open dialogue between patients and healthcare providers to tailor treatment plans that balance efficacy with minimal risk. Kontopidis accentuates the importance of lifestyle behavior change, underscoring the potential of healthy lifestyle choices in mitigating cancer risk.

Quality of Life and Risk Mitigation

Striking a balance between managing psoriasis effectively and minimizing cancer risk is a delicate endeavor. Kontopantelis suggests that maintaining the current course may be advisable if a treatment plan is yielding positive outcomes and enhancing quality of life. However, he emphasizes continuous risk assessment and adaptation of treatment strategies as needed.

Lowering Cancer Risk With Lifestyle Modifications

While elucidating the increased cancer risk associated with psoriasis, the research team also sheds light on the potential of lifestyle modifications in risk mitigation. Trafford notes that studies accounting for lifestyle factors demonstrated lower cancer risk, underscoring the impact of healthy lifestyle choices.

Healthy Lifestyle

The researchers advocate for the adoption of a healthy lifestyle as a means to lower cancer risk, irrespective of psoriasis status. Steering clear of smoking, moderating alcohol intake, maintaining a healthy weight, and embracing a balanced diet are pivotal lifestyle modifications that can protect against cancer.

Empowering Individuals

Ultimately, the researchers emphasize the empowerment of individuals through knowledge and proactive measures. Multifactorial cancer risk requires a comprehensive approach that includes lifestyle changes and medicinal therapies. Psoriasis patients should talk to their doctors, try tailored treatments, and live healthily.
