Skin Cancer Check Up
Squamous Cell Carcinoma
Squamous cell is the second most common skin cancer.
Can be superficial, keratoacanthomas, or invasive.
Forms on ear, face, neck, arms, chest, and back.
Looks like a firm red bump, a re-opening sore, or scaly patch on the skin.
Melanoma
Melanoma is the least common skin cancer.
It can be very deadly.
It is the most likely to metastasize or spread to other parts of the body and cause death.
Arises from melanocytes which are cells that give us pigment, they make us tan and have more melanin.
Look for a black or brown mole like thing or a bump on the skin.

What is Skin Cancer?
Skin cancer is the uncontrolled growth of cells. This is usually caused by UV rays from the sun or tanning beds.

It can come in three main forms:
Basal cell
Squamous cell
Melanoma

The best ways you can protect against skin cancer is by covering up with clothing or wearing sunscreen.
Basal Cell Carcinoma
Basal cell is the most common type of skin cancer.
It can be superficial, nodule, or invasive.
Usually develops in people with fair skin.
Develop after years of sun exposure or indoor tanning.
Common on head, neck, and arms but can be anywhere.
Looks like a pearl shaped flesh-colored bump, or pinkish spot on skin
Of all the cancers, skin cancer is the most common in the US

1 in 5 Americans are diagnosed with skin cancer in a lifetime

About 3.5 million skin cancers are diagnosed in 2 million people each year

A 2005 study revealed that basal cell carcinoma and squamous cell carcinoma are increasing in men and women under 40. They also found that basal cell carcinoma increased faster in young women than in young men

About nine thousand people die from melanoma each year

Sunscreen
Sunscreen may be what is protecting you, but it does have a negative impact if you buy chemical sunscreen.

Coral reefs are in danger for many reasons, one of which is sunscreen. 6,000 tons of sunscreen wash into coral reefs each year.
Most sunscreens contain oxybenzone which bleaches and damages coral reefs. There are also many other harmful chemicals in non-organic sunscreen products. So, stop harming the reefs and buy natural.
