Stages of melanomas are common and can occur at any stage of the life span.
But the effects are sometimes severe, especially for those at higher risk.
Here are the key stages of melanosis, which may be of particular concern.
Stage 1 melanoma stage 1 melanomas, known as melanomas in some countries, are the most aggressive and common types of melanocytic melanoma.
They are the result of a mutation in the melanocyte, the white blood cells that normally produce melanin.
This mutation can cause a mass of cells called a malignant melanoma or a diffuse or subcutaneous malignant tumour.
Stage 2 melanoma Stage 2 tumours are less aggressive and may not require surgical removal.
The most common stage is Stage 2, which is more commonly diagnosed in the age group 30-49 years.
Stage 3 melanosis Stage 3 tumours can develop into Stage 4 melanoma if there are too many cells or if there is inflammation or scarring.
These tumours may spread to other parts of the body.
They can also be spread through contact with the blood.
They may also be carried by infected blood or other bodily fluids.
Stage 4 tumours have a much shorter life span than Stage 1 tumours.
Stage 5 melanoma The most serious form of melanoproliferative disease, Stage 5 is the most common and is often diagnosed in people over 50.
Stage 6 melanoma A less aggressive form of stage 3 melanomas which develops when there is too many melanocytes (cells in the skin) to destroy.
Stage 7 melanoma When there are enough cells in a tumour to be removed.
Stage 8 melanoma If there are no other viable tumours to remove.
Stage 9 melanoma This stage is known as Stage 10, where there are not enough cells to kill off all the cells.
Stage 10 melanoma can spread to lymph nodes, joints and other organs.
It is most often diagnosed between the ages of 50 and 70.
Stage 11 melanoma Any tumour which develops after the age of 40, when the number of melanocytes is so low it is difficult to find any cancerous cells.
The stage is best diagnosed after the death of the patient.
Stage 12 melanoma In rare cases, Stage 12 may occur in people with the mutation of the BRCA1 gene.
This gene makes a mutation which makes the body’s own melanocortin receptor receptor more likely to produce melanocytes.
This means that Stage 12 tumours tend to be more aggressive and can spread faster.
Stage 13 melanoma After Stage 13 tumours, Stage 14 melanoma occurs when there are more than 200,000 melanocytes in a person’s blood.
Stage 15 melanoma These tumour-inducing tumours occur when the body has so many cells that they are unable to destroy them.
Stage 16 melanoma People who have had Stage 16 tumours also have Stage 16b tumours which are very aggressive and very common.
They occur when there has been a mutation of one of the gene involved in producing the melanocollin receptor.
Stage 17 melanoma At this stage, there are about 2,000,000 cells in the body that can produce melanoma cells.
People with Stage 17 tumours often have a higher risk of developing Stage 18 melanoma which occurs when the cells do not produce enough melanocells to kill the tumour, or they have not been removed enough.
Stage 18 tumour The most aggressive stage of stage 18 melanomas occurs when only one-third of the cells in your body produce melanocolls.
Stage 19 melanoma Where the tumours develop at an advanced stage, they are thought to have a greater risk of spreading to other organs and tissues.
The risk is highest when the tumouring site is near the liver.
The tumour can spread from there to the lungs, heart and brain.
Stage 20 melanoma Tumours that develop in people who have already had Stage 19 tumours and are not treated.
Stage 21 melanoma On the other hand, Stage 21 tumours do not spread, but are more likely than others to spread to the heart, lungs and other vital organs.
Stage 22 melanoma Many people with Stage 22 tumours die from complications from Stage 22.
The majority of patients die from cancer.
Stage 23 melanoma You are at increased risk of dying from cancer if you have Stage 23.
Stage 24 melanoma More aggressive tumours appear when the disease has spread to a bone or other organ.
Stage 25 melanoma It is more common in people between the age 15 and 45 years.
If you are 65 or older, you are more at risk of death.
Stage 26 melanoma Most of the time, people with stage 26 melanomas do not die from the disease, but die from a type of cancer called non-Hodgkin lymphoma.
Stage 27 melanoma There are fewer people with advanced melanoma
