Skin Cancer Symptoms and Causes You Shouldn’t Ignore

Skin cancer is one of the most common forms of cancer globally. In sun-rich regions like Indonesia, it is a growing concern due to high year-round ultraviolet (UV) exposure.

While it’s often preventable and highly treatable when caught early, skin cancer is frequently overlooked, especially when early symptoms seem harmless. Understanding what causes skin cancer and how to recognize the warning signs can help people seek treatment early and reduce long-term health risks.

Whether you live in Indonesia or are visiting, learning about skin health is a smart way to protect yourself in this tropical environment.

What Causes Skin Cancer in Indonesia?

The biggest cause of skin cancer is prolonged and unprotected exposure to ultraviolet (UV) radiation from the sun. In equatorial areas like Bali and other parts of Indonesia, UV levels remain high throughout the year, increasing the risk of skin cell damage.

Several other factors can also increase your chances of developing skin cancer:

• Genetic susceptibility: Family history of skin cancer may increase risk.
• Skin type: People with fair or light skin have less melanin and are more vulnerable to UV damage.
• Outdoor work: Farmers, construction workers, and others who spend long hours under the sun without proper protection face higher risks.
• Chemical exposure: Prolonged contact with certain chemicals in cosmetics or medications may increase skin sensitivity.
• Lifestyle factors: Smoking and a weakened immune system have been linked to a higher chance of developing skin cancers.
• Age: Risk increases with age, particularly among those over 45.

Early detection and regular skin evaluations are key to managing risk. Bali International Hospital offers professional dermatology care focused on prevention and timely diagnosis.

Common Symptoms of Skin Cancer

Early signs of skin cancer often appear as minor changes in the skin’s texture or color. Being aware of these warning signs can help detect problems before they become serious.

Here are the most common symptoms:

• Rough, scaly, or raised patches on sun-exposed areas
• Dome-shaped or pink lumps that may bleed or crust
• Flat red or brown lesions that do not heal
• Dark patches or moles with irregular borders
• Rapid changes in existing moles, such as size, shape, or color
• New skin growths that look different from others
• Itching, bleeding, or tenderness in one spot over time

If you notice any of these changes, even if they seem small, it’s best to consult a skin specialist. A quick, painless check-up can offer peace of mind or ensure timely treatment.

Types of Skin Cancer in Indonesia

There are several forms of skin cancer, each with its own symptoms and levels of severity. The most common types seen in Indonesia include:

Basal Cell Carcinoma (BCC)

• The most frequent form
• Appears on sun-exposed areas like the face, ears, and neck
• Often presents as a pearly or waxy bump
• Grows slowly and rarely spreads, but early removal is important

Squamous Cell Carcinoma (SCC)

• Appears as a red, scaly patch or firm bump
• Often found on the hands, scalp, ears, and lips
• Can grow deeper into the skin and may spread if untreated

Malignant Melanoma

• Less common, but the most dangerous
• Can develop from existing moles or as a new dark spot
• Changes shape, size, or color quickly
• Requires immediate treatment as it can spread rapidly to other parts of the body

Early diagnosis helps improve outcomes, particularly for more aggressive cancers like melanoma.

Who Is at Risk?

Anyone can develop skin cancer, but certain people may be at higher risk:

• People with light or fair skin
• Older adults, particularly those between ages 45–64
• Individuals with frequent sun exposure, including:
• Workers
• Athletes
• Hobbyists
• People using medications that increase photosensitivity
• Those with weakened immune systems due to illness or medical treatments



Protective clothing, sunscreen use, and regular skin checks are essential steps for everyone, especially those who spend time outdoors.

The Importance of Early Detection

Most skin cancers can be cured if identified and treated in their early stages. This is why early detection is critical.

Skin exams should be part of your routine health check, especially if you have risk factors or notice new skin changes. Here’s how to improve early detection:

• Check your skin monthly for unusual moles, spots, or growths
• See a dermatologist if anything changes in appearance, size, or texture
• Get professional skin checks annually, particularly if you live in or frequently visit tropical regions

A trained medical team can use tools like dermoscopy or biopsy to evaluate suspicious lesions with precision. Protect your health - schedule a consultation with our dermatology team today.
