Itchiness, or pruritus, is an irritating sensation that makes you want to scratch your skin. Everyone experiences itchiness from time to time. Bug bites, poison ivy, a reaction to the sun, there are a number of things that cause it! Persistent itching, however, can be particularly bothersome and may indicate an underlying health issue. Research shows that about 40% of skin cancer cases involve itchiness. This is especially true for nonmelanoma skin cancers like basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which are the most common types.
Why Does This Happen?
The exact reason why skin cancer causes itchiness isn't fully understood, but there are a few possible explanations.
- Inflammation: Skin cancers often cause inflammation, which can lead to an itchy sensation.
- Nerve Irritation: As cancer grows, it can affect the nerves in the skin, causing them to send itch signals to the brain.
- Tissue Changes: Cancer can cause changes in skin tissues that might lead to itching.
While not all itchy skin is a sign of cancer, persistent itching in a specific area should be checked by a dermatologist. This is especially true if accompanied by other changes such as a new growth, a sore that doesn’t heal, or a change in a mole.
Finding Relief
If you are experiencing itchy skin due to skin cancer, there are several steps you can take to find relief.
1. Consult Your Doctor
The first step is to see a dermatologist who can diagnose the cause of your itchiness. If it’s related to skin cancer, your doctor can recommend the best course of treatment. They may prescribe medications or recommend procedures to treat the cancer and alleviate symptoms. Stress can make itching worse. Practice relaxation techniques such as deep breathing, meditation, or yoga to help manage stress levels.
2. Moisturizer and Hydrate
Keeping your skin moisturized can help reduce dryness and irritation. Use hypoallergenic, fragrance-free moisturizers to avoid further irritation. Keeping your body well-hydrated can also help maintain healthy skin and can reduce itchiness.
3. Avoid Irritants
Use mild soaps and detergents to avoid irritating your skin. Wear protective clothing and use sunscreen to protect your skin from further damage.
4. Medications
Products containing hydrocortisone or calamine lotion can provide temporary relief from itching. Applying a cool, damp cloth to the itchy area can help soothe your skin. Over-the-counter antihistamines can help reduce itching caused by allergic reactions. In some cases, your doctor may prescribe stronger medications to control severe itching.
When to Seek Help
If you notice persistent itching along with any of the following symptoms, seek medical attention:
- A new growth or lump on your skin
- A sore that doesn’t heal
- Changes in the size, shape, or color of a mole
- Unexplained weight loss or fatigue
Itchiness can be more than just a minor annoyance. Understanding why it happens and taking steps to find relief can help you manage this symptom effectively. Always consult a dermatologist if you have persistent itching or other changes in your skin to ensure proper treatment. By staying informed and proactive, you can take better care of your skin and overall health.
