Melanoma: Skin Cancer
Melanoma is an uncommon kind of skin malignant growth that is serious. This is also known as a black tumor. The disease is caused when melanocytes; color-creating melanin cells, start to transform and isolate wildly. This skin disease is significant because of the inclination to spread to different pieces of the body which can cause major sickness and passing. Shade cells create in the skin however melanomas are dangerous in specific regions like the chest, back, face or legs. Seldom melanomas can happen in eyes or digestion tracts. Fair complexion individuals (Caucasian) are more in danger than more obscure skin individuals.
Melanoma is quite possibly the most widely recognized malignant growth in youngsters under 30, particularly in young ladies. The melanoma rate has significantly expanded throughout recent years. It's generally acknowledged that expanding levels of bright (UV) openness is one of the principal purposes behind this fast ascent in the number of melanoma cases.
Cause for Melanoma
Melanoma occurs when the pigment-producing cells (melanocytes) are damaged at the DNA level and new cells begin to grow uncontrollably. A mix of variables causes melanoma which incorporates hereditary elements, exposure to UV radiation as well as ecological elements. People with the below factors are at high risk of developing melanoma.
Tendency to develop freckles or high density of freckles due to exposure to the sun
Moles majorly 5 or more atypical moles
A type of brown birthmark known as giant congenital melanocytic nevi
Skin that does not tan easily and looks pale
People with light eye color
People with red or light hair
high sun exposure if it produces blistering sunburn or sun exposure, is intermittent
old age people
a family history of melanoma
People who recently got an organ transplant
Stages of Melanoma
Stage 0 – This is referred to as in situ melanoma. In this stage, the disease is present just in the peripheral layer of the skin.
Stage 1 – Cancer increases in size up to 2mm thick. It is limited to a single place and is not spread yet to lymph nodes.
Stage 2 – In this stage, the cancer is between 1mm to 4mm thick. It may or may not be ulcerated.
Stage 3 – This is the stage where it spreads to one or more lymph nodes or nearest lymphatic channels. Sometimes original cancer may not be visible. If it is visible it might be approx 4mm thick and ulcerated.
Stage 4 – In this stage cancer might be spread to distant lymph nodes or organs like the brain, liver, or lungs.
The situation may worsen and the treatment becomes harder as the stages of cancer advance.
Symptoms of Melanoma
As per the American Academy of Dermatology's "ABCDE," the warning signs of your skin melanoma include:
Asymmetry: One half does not match the other half.
Border: The edges are not smooth.
Color: The color is mottled and uneven, with shades of brown, black, gray, red, or white.
Diameter: The spot is greater than the tip of a pencil eraser (6.0 mm).
Evolving: The spot is new or changing in size, shape, or color.
Your doctor would recommend various tests and procedures to diagnose melanoma including:
Physical exam: Your primary care physician will enquire about your health history and analyze your skin to search for signs that might show melanoma.
Computed Tomography (CT) scan: This helps determine if melanoma is in your internal organs.
Magnetic Resonance Imaging (MRI) scan: This is used to check for melanoma tumors in the brain or spinal cord.
Positron Emission Tomography (PET) scan: A PET scan can check for melanoma in lymph nodes and other parts of your body distant from the original melanoma skin spot.
Blood work: The doctor would run blood tests to measure lactate dehydrogenase (LDH) before treatment. Some other tests include blood chemistry levels and blood cell counts.
Removing a sample of tissue for testing (biopsy): To confirm if a suspicious skin lesion is a melanoma, your healthcare provider might suggest removing a sample of skin for testing. Commonly, the punch biopsy is done with a circular blade that's pressed into the skin around the suspicious mole. Sometimes, excisional biopsy is used that required a scalpel to cut away the entire mole and a small margin of healthy tissue around it.
Treatment of Melanoma
The treatment of melanoma is similar to different malignant growths. Sometimes, unlike numerous malignant growths inside the body, it is easier to access the cancerous tissue and eliminate it. Thus, surgery is the standard treatment choice for melanoma.
The treatment of melanoma include:
Melanoma Surgery: This is beneficial in the early stages as surgery has a high probability to cure your melanoma.
Lymphadenectomy: In situations where melanoma has spread, the expulsion of the lymph nodes close to the primary diagnosed site might be required. This can prevent the spread to a different region of your body.
Metastasectomy: This is used to remove small melanoma bits from organs.
Targeted cancer therapy: The drugs are used to attack specific cancer cells, leaving healthy cells untouched.
Radiation Therapy: This includes treatments with high-energy rays to attack cancer cells and shrink tumors.
Immunotherapy: This would stimulate your immune system to help fight cancer.
Unlike other cancer inside the body, it is easier to access the cancerous tissues and remove them completely. Thus, surgery is done before various therapies to remove the cancerous tissue. Surgery not only removes the cancerous tissue but also nearby non-cancerous tissue so that cancer may not develop again.
In case melanoma has spread to a large area of skin cells doctors prefer a skin graft to remove the cancerous tissues.
Prevention: It is important to prevent the formation of melanoma as the treatment is painful to the patient. Also, there is a risk of reoccurrence of the cancerous tissue. Some of the common things to be avoided are:
Exposure to sunlight – UV light exposure especially caused during tanning booths is a major reason for melanoma. Reducing UV radiation exposure by wearing opaque clothes or applying sunscreen will reduce the risk of developing melanoma.
Examining Skin – It is important to examine the skin regularly for new skin growths or changes in existing moles, freckles, bumps, and birthmarks.
Treatment of tumors depends on their thickness. For small and medium-sized tumors the ideal biopsy technique is complete full-thickness excision of the tissue.
Most melanoma can be cured before they have an opportunity to spread. But, further advanced stages of melanoma can be fatal. The initial stage of melanoma can be diagnosed and eliminated, increasing your opportunities for a full recovery.
