Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesn't heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma. A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesn't heal, or a change in a mole.
Any change in size, shape, color or elevation of a spot on your skin, or any new symptom in it, such as bleeding, itching or crusting, may be a warning sign of melanoma.
Pigment, redness or swelling that spreads outside the border of a spot to the surrounding skin. Itchiness, tenderness or pain. Changes in texture, or scales, oozing or bleeding from an existing mole. Blurry vision or partial loss of sight, or dark spots in the iris.
The first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs. Melanomas can develop anywhere on your body.
General symptoms
hard or swollen lymph nodes. hard lump on your skin. unexplained pain. feeling very tired or unwell.
Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body.
Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen. Diameter: There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea (larger than 6 millimeters or about 1/4 inch).
Blood tests. Blood tests aren't used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
Signs and symptoms
The characteristics of melanoma (known by the acronym ABCDE) include the following: A: Asymmetry. B: Irregular border. C: Color variations: Especially red, white, and blue tones in a brown or black lesion.
How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.
What are the signs of late-stage skin cancer? Melanoma is considered stage 4 when it has metastasized to lymph nodes in a part of the body far from the original tumor or if it has metastasized to internal organs like the lungs, liver, brain, bone or gastrointestinal tract.
Stage 1 is part of the number staging system and means your melanoma is at an early stage. It is only in the skin and there is no sign that it has spread to lymph nodes or other parts of the body. Stage 1 can be divided into 1A and 1B.
This is a noninvasive stage, which is also called melanoma “in situ,” meaning “in its original place.” With stage I melanoma, the tumor's thickness is 1mm or less. This tumor may or may not have ulcerated, and it isn't yet believed to have spread beyond the original site.
Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.
When stage 4 melanoma is diagnosed after a scan, there may be no symptoms at all, and it can be difficult to believe the cancer has spread. However, people with stage 4 melanoma may have a very wide range of symptoms. People who have melanoma diagnosed in the brain are told not to drive.
How fast does melanoma spread and grow to local lymph nodes and other organs? “Melanoma can grow extremely quickly and can become life-threatening in as little as six weeks,” noted Dr. Duncanson.
The general symptoms of advanced melanoma include: weight loss. loss of appetite. feeling very tired (fatigued).
You can have melanoma without feeling any pain or discomfort. For many people, the only sign of this skin cancer is a spot that has some of the ABCDEs of melanoma or a line beneath a nail. Sometimes, melanoma causes discomfort.
Metastatic melanoma most often spreads to the lymph nodes, brain, bones, liver or lungs, and the additional symptoms experienced at this late stage will depend on where the melanoma has spread. For example: Lungs – A persistent cough or shortness of breath. Brain – Headaches or seizures.
Metastatic melanoma symptoms and signs may include: Fatigue. Swollen or painful lymph nodes. Weight loss.
