Before discussing various reasons that cause a mole to grow on your skin, let’s first quickly understand what makes them grow on your skin at the first place. To put it simply, melanocyte is a melanin-producing cell that is located on the bottom of the upper layer of the skin called epidermis.  They are spread throughout your skin and are responsible for giving skin its natural color.

When these melanocytes grow in clusters or groups rather than individually, the pigmentation appears to be dark because of the concentration of color producing cells at one place. This is referred to as a mole.

According to a report by Cleveland clinic, it is normal for any individual to have up to 40 moles throughout their life. Most moles are benign overgrowths of skin cells, however, if they appear to be different in shape, size or structure, it is important that you get it examined by your dermatologist just to make sure everything is fine and the mole is not cancerous. It does not matter if a mole is flat or raised, black or brown, each mole has the potential to turn into melanoma.

Not one, there are a lot of reasons that are responsible for the occurrence of moles on our skin. Obviously, there are some which you do not have a control over such as Congenital Nevis (or moles appearing at birth) but some can clearly be avoided by keen observation and consulting your medical expert once every month.

Among others, following are the most common reasons that cause a mole to grow on your skin.

1. At birth

Mole that appears on birth is also called Congenital Nevi. They are mostly benign. It is also believed that one in 100 people attract Congenital Nevis. You should keep a check on this mole as this has high chances of converting to melanoma over the course of time.

2. Hereditary

It may be there because someone in your blood relation has it already. A large number of moles on your body due to genetic reasons will increase the likelihood of developing into melanoma, type of skin cancer. It is recommended that you know your moles. Whether or not you want to remove it is a different topic of discussion.

3. Sun Exposure

As we understand that a mole is nothing but the uncommon growth of skin cells called melanocytes, that produces melanin (pigment for skin color). And, when our bodies are exposed more frequently to direct sunlight, melanocytes produce more melanin. Exposure to the sun is one of the most common causes of moles. Existing moles also get darker with more exposure to sunlight. Avoiding sunlight or using good quality sunscreens (SPF greater than 15) can help reduce the growth of new moles and change in existing moles.

5. Pregnancy

Similar to puberty, pregnancy is also a stage when a body goes through several hormonal changes. And, when a body goes through hormonal changes, a mole grows.

Hope this clarifies any doubts that you may have regarding the occurrence of moles. Pls make sure that you try to minimize the causes that allow moles to surface on your body.
