We should warn you that if you have two moles side by side, one of them can be a potential skin cancer. For instance, one of them is a little darker than the surrounding skin, symmetrical and oval shaped, while the second one has irregular borders and it looks like a blood spot that never heals. If you notice characteristics like bleeding, lack of healing and irregularity, make sure to consult a dermatologist because they can be an indicator of something malignant.
Collections of pigment on the skin that develop anywhere on the body are moles or nevi and in most of the cases they are harmless. Nevertheless, in some cases, a mole can actually be the beginning of a skin cancer. Fair and red-headed people have greater chances of developing skin cancer, but this is not a rule since anyone can get it.
There are 3 main types of skin cancer:
1. Basal cell carcinoma
One of the most diagnosed skin cancers is basal cell carcinoma usually found on areas of the body that are often exposed to the sun, including the nose, the whole face and the backs of the hands. This is also not a rule since skin cancer can appear anywhere on the body.
This type of cancer is slow-growing and rarely metastasizes, but if not treated on time it can be disfiguring. There are several kinds of BCC, and they present in different ways. Among them are:
- A hard, pale, scar-like growth that feels waxy.
- A sore that constantly bleeds, oozes, forms a crust and craters.
- Certain growth on the skin whose color is like the surrounding skin or pinkish. Blood vessels can be usually seen inside it.
- Scaly and shiny patch on the skin which can be both red and pink and it is usually mistaken for eczema.
2. Squamous cell carcinoma (SCC)
SCC or commonly known as Sqamous cell carcinoma is a type of skin cancer as well that appears on the areas of the skin which have suffered years of sun damage. Nevertheless, a person can develop this particular type of cancer anywhere on the body, even inside of the mouth. As opposed to basal cell carcinoma, squamous cell carcinoma can metastasize. Signs of SCC are: A sore that either won’t heal, but heals temporarily and comes back.
- Rarely, SCC starts under a nail and destroys the nail as it grows.
- A rough-feeling lump or bump on the skin that grows into a dome. The dome often bleeds and crusts over.
- A flat, reddish, slow-growing scaly patch.
The most dangerous type of cancer among all of them is melanoma and people usually make a mistake thinking that it is just a normal mole. However, in case of malignancy, you will notice the following signs:
The mole has different colors. When it comes to normal moles, they can have many different colors such as blue, red, pink, but still they must be one even color.
- The mole is asymmetrical. If you cut it in half, one-half is larger.
- It has irregular or fuzzy borders. Just like other skin cancers, melanomas can bleed as well and never heal. Moreover, they can also hurt and itch.
- The mole is bigger around than a pencil eraser and growing.
- As opposed to basal cell carcinomas, melanomas tend to grow faster.
