Introduction

What Is Skin Cancer?

Skin cancer is a disease where abnormal skin cells grow uncontrollably. It happens when skin cells are damaged, often by ultraviolet (UV) radiation from sunlight or tanning beds. This damage can cause cells to multiply rapidly and form tumors.

Why Is It Important to Learn About Skin Cancer?

Skin cancer is the most common type of cancer worldwide. Knowing about skin cancer is important because:

• Early Detection Saves Lives: When found early, most skin cancers can be cured.
• Prevention Is Possible: Many cases are preventable through simple sun safety practices.
• Rising Rates: Skin cancer rates have been increasing due to more time spent in the sun and the popularity of tanning beds.

Recent Developments:

• Improved Treatments: Advances in treatments like immunotherapy have increased survival rates for advanced melanoma, the most serious type of skin cancer.
• Awareness Campaigns: Public health campaigns are educating people about the dangers of UV exposure and how to protect their skin.

Statistical Overview

• Prevalence: About 1 in 5 Americans will develop skin cancer by age 70.
• Annual Cases: Over 5 million cases of skin cancer are diagnosed in the United States each year.
• Types of Skin Cancer:
  • Basal Cell Carcinoma (BCC): Accounts for about 80% of skin cancer cases.
  • Squamous Cell Carcinoma (SCC): Makes up about 16% of cases.
  • Melanoma: Less common (1% of cases) but more dangerous due to its ability to spread to other parts of the body.
• Mortality Rates:
  • Melanoma: Causes the majority of skin cancer deaths.
  • Approximately 7,000 Americans die from melanoma each year.
• Survival Rates:
  • Early Detection: The 5-year survival rate for melanoma detected early is over 99%.
  • Advanced Melanoma: Survival rates decrease significantly if the cancer has spread.
• Trends and Disparities:
• Increasing Incidence: Skin cancer rates have been rising over the past few decades.
• Age Factors: While skin cancer can occur at any age, the risk increases as you get older.
• Geographic Differences: Higher rates are found in areas with intense sunlight, like Australia and the southern United States.
• Gender Differences:
  • Before Age 50: Melanoma rates are higher in women.
  • After Age 50: Rates are higher in men.

Risk Factors and Prevention

Known Risk Factors

1. Ultraviolet (UV) Radiation Exposure:
   • Sun Exposure: Spending a lot of time in the sun without protection increases your risk.
   • Tanning Beds: Using indoor tanning devices exposes you to harmful UV rays.
2. Fair Skin:
   • People with light skin, freckles, blond or red hair, and light-colored eyes have less melanin, which means less natural protection against UV radiation.
3. History of Sunburns:
   • Having had one or more blistering sunburns, especially during childhood or adolescence, increases your risk.
4. Moles:
   • Having many moles or unusual moles called dysplastic nevi can increase your risk of melanoma.
5. Family History:
   • If a parent, sibling, or child has had skin cancer, your risk is higher.
6. Personal History:
   • If you’ve had skin cancer before, you’re at higher risk of developing it again.
7. Weakened Immune System:
   • Conditions like HIV/AIDS or medications that suppress the immune system can increase risk.
8. Age and Gender:
   • Age: Risk increases with age due to cumulative sun exposure.
   • Gender: Men are more likely to develop BCC and SCC, while women under 50 are more likely to develop melanoma.

Prevention

Protecting Your Skin from the Sun:

• Use Sunscreen:
  • Apply a broad-spectrum sunscreen with at least SPF 30 every day.
  • Reapply every two hours, or after swimming or sweating.
• Wear Protective Clothing:
  • Long-sleeved shirts, pants, wide-brimmed hats, and UV-blocking sunglasses.
• Seek Shade:
  • Especially between 10 a.m. and 4 p.m., when the sun’s rays are strongest.
• Avoid Tanning Beds:
  • They emit harmful UV radiation that increases cancer risk.

Regular Skin Checks:

• Self-Examinations:
  • Check your skin once a month for new or changing moles or spots.
• Professional Exams:
  • Visit a dermatologist annually for a full-body skin exam.

Healthy Lifestyle Choices:

• Vitamin D:
  • Get vitamin D safely through diet and supplements, not through sun exposure.
• Avoid Smoking:
  • Smoking can weaken your immune system and increase cancer risk.

Remember: Prevention is key. Protecting your skin from UV rays reduces your risk of developing skin cancer.

Screening

Symptoms and Signs

Early-Stage Symptoms:

• A Lump or Nodule in the Neck:
  • Often painless, you might feel a lump when touching your neck.
• Hoarseness or Voice Changes:
  • Persistent hoarseness not linked to a cold or allergies.

Advanced Stages:

• Difficulty Swallowing:
  • Feeling like food is stuck in your throat.
• Difficulty Breathing:
  • Shortness of breath or wheezing.
• Swollen Lymph Nodes:
  • Especially in the neck area.

Note: These symptoms can also be caused by non-cancerous conditions. However, if you experience any of these signs, it’s important to see a healthcare provider for evaluation.

Diagnosis

Diagnostic Process:

After Diagnosis:

Staging Tests:

• Eat a balanced diet rich in fruits, vegetables, and lean proteins.
• Stay hydrated and consider consulting a nutritionist.

Understanding Results:

• Benign (Non-Cancerous):
  • No cancer cells found.
• Malignant (Cancerous):
  • Treatment plan will be discussed.

Don’t Delay: If advised to get a biopsy, it’s important to do so promptly for the best outcomes.

Stages

Types of Treatment

Overview of Treatment Modalities

1. Surgery:
   • Excisional Surgery:
     • The cancerous tissue and a margin of healthy skin are removed.
     • Outcome: Often cures early-stage skin cancers.
     • Side Effects: Possible scarring; risk of infection is low.
   • Mohs Surgery:
     • Layers of skin are removed and examined until no cancer cells remain.
     • Outcome: High cure rate; preserves as much healthy skin as possible.
     • Side Effects: Minimal scarring; done under local anesthesia.
2. Radiation Therapy:
   • How It Works:
     • Uses high-energy rays to destroy cancer cells.
   • When Used:
     • For cancers that can’t be removed surgically.
     • When surgery isn’t an option due to health reasons.
   • Side Effects:
     • Skin irritation, redness, fatigue in the treated area.
3. Chemotherapy:
   • Topical Chemotherapy:
     • Creams or lotions applied directly to the skin.
     • Used For: Superficial skin cancers.
     • Side Effects: Redness, swelling, sensitivity at application site.
   • Systemic Chemotherapy:
     • Drugs taken orally or injected that travel throughout the body.
     • Used For: Advanced skin cancers.
     • Side Effects: Nausea, hair loss, fatigue, increased infection risk.
4. Immunotherapy:
   • How It Works:
     • Boosts the body’s immune system to fight cancer.
   • Drugs Used:
     • Pembrolizumab (Keytruda), Nivolumab (Opdivo).
