What is malignant melanoma?
Malignant melanoma is a tumor of skin cells producing pigment. Pigment cells are placed throughout the dermis (skin) and give the color of the skin. Pigment cells are more strongly concentrated in the moths. When one of these pigment cells becomes malignant, it produces a tumor called melanoma. Melanomas can occur anywhere; In parts of the skin that previously looked normal or in moths that have been present for a long time.
Melanoma is often called skin cancer because it comes from skin cells. This definition is not quite correct because melanoma differs from typical skin cancer in two respects. Not only is melanoma relatively rare, but it can metastasize to other parts of the body, which is typical skin cancer normally. Due to this tendency to spread, patients with melanoma are usually referred to as treatment experts.
What usually means the term "skin cancer" is a common tumor called basal cell cancer. These tumor types tend to spread and are usually cured by simpletreatments such as excision (surgery) or cryosurgy (freezing). It is believed that melanoma is more common in people who have received a number of blisters in their childhood.
Melanoma is not contagious and cannot be transmitted by physical contact. However, because of their genetic make -up or inherited skin color, children of patients with melanoma tend to have a slightly increased risk of melanoma.
When melanoma spreads, some of its malignant cells attack either local blood vessels or lymphatic blood vessels that carry lymphatic fluid into the lymph nodes. If malignant cells attack lymphatic blood vessels, their liquid can transfer them to the lymph nodes. If malignations attack blood vessels, they can be transferred by blood to distant parts of the body.
When melanoma spreads, the most likely place to be rediscent is in the lymph nodes that are closest to the originalhim to the tumor place. For example, if the primary melanoma was on the arm, the nearest lymph nodes would be under the armpits. If the primary tumor was on the leg, the nearest nodes would be weaknesses; For the head there are adjacent lymph nodes in the throat. In the primary melanoma on the trunk, the closest lymph nodes of the weakness or armpits would be the nearest lymph nodes.
In 2002, a staging system for malignant melanoma was developed.
Stage I : Primary Melanoma of a certain size without ulceration, no lymph nodes and no metastases (secondary tumors.)
phase II : primary melanomas that are somewhat larger, but also lacking ulceration, involvement of lymph nodes or metastases.
phase III : metastases to LymuPh nodes or metastases/satellites in transit, without distant metastases.
Stage IV : remote metastases. Melanomas that advance to this phase are often fatal.
with the destruction of ozone inRstva, more harmful ultraviolet (UV) rays reach the skin. The daily use of the sun block with the least Sun protection factor (SPF) 15 can help prevent some skin cancer and premature skin aging.
It is important that everyone is aware of their skin and record any changes, such as small pearl bumps, spots that refuse to heal or change in the moths, and seek treatment from the doctor at the first sign of such changes.
Many skin cancer has a high level of treatment if it is caught early enough.
