Do basal cells turn into squamous cells?
Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skin's surface. As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells.
Can you have basal cell and squamous cell carcinoma?
Therefore, when determining the diagnosis and surgical treatment of patients with skin cancer, we should not rule out the possibility that BCC and SCC may coexist and that basosquamous cell carcinoma may develop even if patients are referred to plastic surgeons after being diagnosed with BCC and SCC in other hospitals ...
Can basal cell carcinoma turn malignant?
Basal cell carcinoma does not progress into melanoma. Each is a separate and distinct type of skin cancer. Basal cell carcinoma is the most common form of skin cancer and one of two major nonmelanoma skin cancer types (the other is squamous cell carcinoma).
Which grows faster basal cell or squamous cell carcinoma?
Squamous cell skin cancer SCC is generally faster growing than basal cell cancers. About 20 out of every 100 skin cancers (20%) are SCCs. They begin in cells called keratinocytes, which are found in the epidermis. Most SCCs develop on areas of skin exposed to the sun.
Can you have two different cancers at the same time?
For example, someone who was treated for a certain type of colorectal cancer can get another type of colorectal cancer as a second cancer.
How quickly does squamous cell carcinoma spread?
Squamous cell carcinoma rarely metastasizes (spreads to other areas of the body), and when spreading does occur, it typically happens slowly. Indeed, most squamous cell carcinoma cases are diagnosed before the cancer has progressed beyond the upper layer of skin.
How do you know if basal cell carcinoma has spread?
Ask your doctor if your lymph nodes will be tested. Basal and squamous cell cancers don't often spread to other parts of the body. But if your doctor thinks your skin cancer might spread, you might need imaging tests, such as MRI or CT scans.
What's worse basal cell or squamous?
Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize).
How long does it take for basal cell carcinoma to spread?
The tumors enlarge very slowly, sometimes so slowly that they go unnoticed as new growths. However, the growth rate varies greatly from tumor to tumor, with some growing as much as ½ inch (about 1 centimeter) in a year. Basal cell carcinomas rarely spread (metastasize) to other parts of the body.
What does the beginning of squamous cell carcinoma look like?
Squamous cell carcinoma initially appears as a skin-colored or light red nodule, usually with a rough surface. They often resemble warts and sometimes resemble open bruises with raised, crusty edges. The lesions tend to develop slowly and can grow into a large tumor, sometimes with central ulceration.
How does squamous cell carcinoma start?
Most squamous cell carcinomas of the skin result from prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds or lamps. Avoiding UV light helps reduce your risk of squamous cell carcinoma of the skin and other forms of skin cancer.
How long can you wait to treat squamous cell carcinoma?
The median patient delay was 2 months. The highest quartile patients reported > 9 months between noticing the lesion and the first visit, defined as long patient delay. The median treatment delay was 2 months. The highest quartile patients reported > 4 months treatment delay, defined as long treatment delay.
How can you tell the difference between basal cell and squamous cell carcinoma?
Basal cell carcinoma most commonly appears as a pearly white, dome-shaped papule with prominent telangiectatic surface vessels. Squamous cell carcinoma most commonly appears as a firm, smooth, or hyperkeratotic papule or plaque, often with central ulceration.
What is Stage 4 squamous cell carcinoma?
Stage 4 SCC indicates cancer spread to distant sites, such as organs, distant lymph nodes and other structures.
What organs does squamous cell carcinoma affect?
If left untreated, squamous cell carcinoma can spread to nearby lymph nodes, bones or distant organs (such as the lungs or liver). Normal squamous tissue usually appears flat. When this tissue develops cancer it can appear as round masses that are can be flat, raised, or ulcerated.

What is the name of the cancer that occurs when a cell moves upward?
As new cells move upward, they become flattened squamous cells, where a skin cancer called squamous cell carcinoma can occur. Melanoma, another type of skin cancer, arises in the pigment cells (melanocytes). Basal cell carcinoma occurs when one of the skin's basal cells develops a mutation in its DNA.
What are the factors that increase the risk of basal cell carcinoma?
Factors that increase your risk of basal cell carcinoma include: Chronic sun exposure. A lot of time spent in the sun — or in commercial tanning beds — increases the risk of basal cell carcinoma.

As new cells move upward, they become flattened squamous cells, ...
How many stages of squamous cell carcinoma are there?
According to the Moffitt Cancer Center, squamous cell carcinoma is classified into stages from 0-4 according to how far it has spread throughout the body. Stage 0 means it hasn’t spread beyond the top layer of skin. Stage 1 squamous cell has spread deeper into the skin but has not spread into healthy tissue or lymph nodes.
What is the difference between stage 3 and 4 squamous cell?
Stage 3 means that the cancer has spread to lymph nodes, and Stage 4 squamous cell has spread to at least one organ, such as a separate area of the skin, the lungs, or the brain.
What is the second most common type of skin cancer?
The second most common type of skin cancer is squamous cell carcinoma. Squamous cell carcinoma is also frequently caused by sun exposure or tanning bed use. Like basal cells, squamous cells can grow deep into the skin.
Can basal cell carcinoma spread?
Basal cell carcinoma is a slow-growing cancer, but early treatment is important because, if left untreated, basal cell carcinoma can spread and grow deep into the skin. My surgeon told me many years ago that, what appears to be a small area of basal cell carcinoma on the surface of the skin, can actually be as large as a silver dollar in other layers of the skin.
Where does basal cell carcinoma start?
Basal cell carcinoma begins in the basal cells —a type of cell within the skin that produces new skin cells as old ones die off. Basal cell carcinoma often appears as a slightly transparent bump on the skin, though it can take other forms.
Where does squamous cell carcinoma occur?
Squamous cell carcinoma develops in the thin, flat squamous cells that make up the outer layer of the skin. Squamous cells are found all over the body, and this type of cancer can occur anywhere squamous cells are found. Though this form of skin cancer is not usually life-threatening, one major difference between basal cell and squamous cell cancers is that squamous cell cancer are more likely to grow deeper into the layers of your skin and spread to other parts of the body. While still relatively uncommon, it is considered an aggressive form of cancer, if left untreated.
What is the treatment for basal cell carcinoma?
There are several basal cell carcinoma treatment options available to patients, including Mohs micrographic surgery, excisional surgery, electrosurgery, cryosurgery, and laser surgery. These treatments all have one thing in common: the word surgery.

Where does basal cell carcinoma occur?
Studies reveal that 80% of skin cancers develop from basal cancer cells. The basal cell skin cancer generally develops on the neck and head while also being found anywhere on the skin. Furthermore, the disease is usually caused by the sun’s ultraviolet rays or develops in people who have taken radiation therapy many years ago. Basal cell carcinoma grows relatively slowly and hardly spreads to other parts of the body.
How long does squamous cell carcinoma last?

What are the different types of skin cancer?
Primarily, there are four types of skin cancer: basal cell carcinoma, squamous cell carcinoma, Merkel cell cancer, and melanoma, but basal and squamous cell cancer are the most common types. Let’s find out more about these diseases.
What causes skin cancer?
The mutations that occur in the skin cell DNA causes skin cancer. Such changes cause abnormal cells to multiply uncontrollably. When this occurs in squamous cells, it gives rise to squamous cell cancer. DNA mutations are generally caused by UV radiation found in the sun, tanning lamps, and beds.

Overview
Symptoms
- Basal cell carcinoma usually develops on sun-exposed parts of your body, especially your head and neck. Less often, basal cell carcinoma can develop on parts of your body usually protected from the sun, such as the genitals. Basal cell carcinoma appears as a change in the skin, such as a growth or a sore that won't heal. These changes in the skin (lesions) usually have one of the fo…
Causes
- Basal cell carcinoma occurs when one of the skin's basal cells develops a mutation in its DNA. Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off. The process of creating new skin cells is c…
