Skin cancer: facts and treatment methods
Definition of Skin Cancer
Skin cancer is a malignant tumor that develops from the cells of the epidermis, dermis, or other skin structures. It can arise due to prolonged exposure to ultraviolet radiation, genetic factors, or a weakened immune system. The main signs of skin cancer include the appearance of new growths, ulcers or pits on the skin, changes in the color and size of moles, as well as the emergence of itching, tingling, or pain in a specific area of the skin.
Risk factors for skin cancer development
Skin cancer is an oncological disease, the causes of which are often associated with exposure to ultraviolet radiation from the sun or tanning beds. Other risk factors include genetic predisposition, high doses of radiation, a weakened immune system, the presence of a scar or burn on the skin, as well as prolonged sun exposure without protective measures. It is important to take precautions such as using sunscreen and wearing protective clothing to reduce the risk of skin cancer.
- Ultraviolet radiation: exposure to UV rays from the sun or tanning beds can increase the risk of developing skin cancer.
- Genetic predisposition: the presence of certain genetic mutations may increase the likelihood of developing skin cancer.
- Prolonged radiation exposure: a high dose of radiation, especially during the treatment of previous tumors, can increase the risk of developing skin cancer.
- Weakened immune system: patients with a weakened immune system, such as those with HIV infection or those taking immunosuppressive medications, are at greater risk of developing skin cancer.
- Prolonged sun exposure without protection: excessive exposure to UV rays on the skin without the use of sunscreen can increase the risk of developing skin cancer.
Signs and Symptoms of Skin Cancer
Skin cancer can manifest with various symptoms, including the appearance of a new growth or ulcer on the skin, changes in the size, color, or shape of moles or birthmarks, the emergence of ulcers, scabs, bleeding, or itching that doesn’t go away. It is important to pay attention to changes on the skin, especially if they progress or do not heal over a long period.
Other signs of skin cancer may include changes in skin texture or the appearance of new spots, sores, or lumps. If skin cancer is suspected, it is crucial to consult an oncologist immediately for diagnosis and to establish an accurate diagnosis, allowing for treatment to begin at the early stages of the disease.
- Appearance of new growths or ulcers: Skin cancer may manifest as unusual formations on the skin, which can be nodular or have an ulcerated surface.
- Change in size and shape of moles: Moles that start to change in size, shape, or color may be a warning sign of developing skin cancer.
- Appearance of ulcers, crusts, or bleeding: Non-healing wounds, crusts, or ulcers that do not heal for a long time or bleed may indicate skin cancer.
- Itching and discomfort: The appearance of persistent itching, a feeling of tightness, or pain in the skin area may be a symptom of early-stage skin cancer.
- Changes in skin texture: The emergence of new areas of skin with unusual thickness, roughness, or protrusions may also indicate problems in the skin, including cancerous changes.
The specialists’ view on skin cancer treatment
Experts in the field of skin oncology recommend a comprehensive approach to skin cancer treatment, taking into account the type, stage, and localization of the tumor. Depending on the characteristics of the tumor, surgical removal, radiation therapy, chemotherapy, immunotherapy, or targeted drugs may be used. Combined treatment allows for the best outcomes and reduces the likelihood of disease recurrence.
Experts emphasize the importance of early detection of skin cancer for successful treatment. Regular examinations by a dermatologist and careful monitoring of changes in the skin can help identify the tumor at an early stage, when treatment is more effective.
Methods of Diagnosing Skin Cancer
The diagnosis of skin cancer involves a visual examination of the skin by a dermatologist to determine changes in the shape, color, or texture of lesions on the skin. Additional diagnostic methods may include dermatoscopy, biopsy of lesions for microscopic tissue analysis, as well as other instrumental methods, such as mosaic chromoscopy. Early diagnosis plays a crucial role in the successful treatment of skin cancer, allowing for timely initiation of necessary measures to remove the tumor and treat the patient.
- Visual inspection: The dermatologist examines the surface of the skin to detect changes such as new formations or changes in existing ones.
- Dermatoscopy: The use of a dermatoscope for a more detailed study of pigmentation and the structure of formations on the skin.
- Biopsy: Taking a tissue sample for subsequent examination under a microscope to establish a diagnosis of skin cancer.
- Mosaic chromoscopy: A method based on analyzing the color and structure of the skin using special filters and a carbon chamber.
- Instructional anamnesis: Gathering information about risk factors, previous cases of skin cancer, prolonged exposure to ultraviolet rays, and other important data for diagnosis.
Methods for Treating Skin Cancer
The treatment of skin cancer depends on the type, stage, and extent of the tumor. In skin cancer, surgical removal of the tumor is often the first line of therapy. For some types of skin cancer or in later stages, radiation therapy or chemotherapy may be prescribed. In certain cases, the use of targeted drugs or immunotherapy may also be recommended. Early consultation with a doctor for diagnosis and initiation of treatment increases the chances of complete recovery from skin cancer.
- Surgical treatment: Involves the removal of the tumor and a small portion of healthy tissue around it to prevent recurrence.
- Radiation therapy: Used to destroy cancer cells or control their growth using radiation.
- Chemotherapy: Involves drugs that destroy cancer cells by blocking their ability to divide and grow.
- Immunotherapy: Helps activate the body’s own immune system to fight skin cancer.
- Targeted therapy: Aimed at specific molecules that play a role in the growth and survival of cancer cells to block or destroy them.
Measures to Prevent Skin Cancer
Skin cancer prevention plays an important role in disease prevention. An important measure is to prevent exposure to ultraviolet radiation from the sun by wearing protective clothing, using sunscreen, and avoiding tanning beds. Regular skin check-ups with a dermatologist can also help detect changes in the skin at early stages and start treatment in a timely manner if necessary. It is important to monitor the condition of the skin, pay attention to changes, and consult a specialist promptly if suspicious formations or symptoms are found.
- Avoid prolonged exposure to the sun, especially during peak ultraviolet hours.
- Use high SPF sunscreen and reapply it periodically throughout the day.
- Wear protective clothing, a hat, and sunglasses to prevent direct exposure of your skin to sunlight.
- Avoid visiting tanning beds and artificial ultraviolet sources, which can also increase the risk of skin cancer.
- Regularly examine your skin for changes and suspicious formations, paying attention to new moles, sores, or wounds.
Interesting aspects about skin cancer
Skin cancer includes various subtypes of tumors, such as basal cell carcinoma, squamous cell carcinoma, and malignant melanoma, each with its own characteristics in development and treatment. For example, basal cell carcinoma, while it tends to grow slowly, can invade neighboring tissues, although it metastasizes in a small percentage of cases. Squamous cell carcinoma, on the other hand, can arise from precancerous skin conditions and is often associated with exposure to ultraviolet rays.
An interesting fact is that skin cancer is one of the most common cancers, but in most cases, it can be successfully treated with early detection. Regular screenings and preventive measures, such as protection from sun exposure, play an important role in preventing skin cancer and maintaining healthy skin throughout life.
