Like other types of cancer, carcinomas are abnormal cells that divide without control. They can spread to other parts of the body but don’t always. “Carcinoma in situ” remains in the cells where it started.
Not all cancers are carcinoma. Additional types of cancer that are not carcinomas penetrate the body in various ways. Those cancers begin in other types of tissue, such as:
- Blood vessels
- Immune system cells
- Spinal cord
Types of Carcinoma
Although carcinomas can transpire in multiple parts of the body, you may often discover people talk about these common types of carcinoma:
- Ductal carcinoma in situ (DCIS)
- Basal cell carcinoma
- Squamous cell carcinoma
- Invasive ductal carcinoma
- Renal cell carcinoma
Basal cell carcinoma. This is the most prevalent form of all cancers. It transpires in cells bordering the deepest part of the epidermis/skin outer layer.
You should accept quick treatment for basal cell carcinoma to bypass scars. But only in very rare circumstances does this kind of carcinoma spread to other parts of the body.
Shiny bumps or scars
If you have basal cell carcinoma, it’s possible that you developed it due to too much time in the sun. You may have had several bad sunburns or else spent a lot of time in the sun during your life.
Squamous cell carcinoma. Most individuals think of skin cancer when they hear the terms “squamous cell carcinoma.” And it is true that this type of carcinoma often shows up on the skin.
But squamous cell carcinoma can also be located in other parts of the body, such as cells lining:
- Respiratory tract
- Certain organs
- Digestive tract
When squamous cell carcinoma originates in the skin, you frequently find it on areas that are shown and open in the sun most of the time, such as the:
- Backs of the hands
Squamous cell carcinoma that manifests on the skin is usually caused by spending an excessive time in the sun over the course of your life. This type of skin carcinoma tends to increase and spread more than basal cell cancers. In rare instances, it may spread to the lymph nodes.
Squamous cell carcinomas may crust or bleed and can include:
- Open sores
- Scaly red patches
- Growth with a depression in the middle
- Renal cell carcinoma. This is the most common type of kidney cancer. It regularly grows as a single tumor within the kidney.
Ductal carcinoma in situ (DCIS). This is a disease where cancer cells are found in the ducts of the breast.But in DCIS, cancer has not fully developed or spread into nearby areas. Almost all women diagnosed with this can be cured.
Invasive ductal carcinoma. This kind of breast cancer begins in a milk duct but spreads into the fatty tissue of the breast. It can spread to other parts of the body through the lymph system and bloodstream.
It may be discovered as a suspicious mass through a mammogram by your health provider or during a breast self-exam.
Other symptoms may include:
- Thicker breast skin
- Swelling of one breast
- Rash or redness of the breast
- New pain in one breast
- Dimpling around the nipple or on breast skin
- Nipple pain, nipple turning inward, or nipple discharge
- Lumps in the underarm area
- Adenocarcinoma. This is a type of carcinoma that originates in cells called “glandular cells.” These cells produce mucus and other fluids. The glandular cells are located in different organs in your body.
Adenocarcinomas can transpire in various parts of the body. Some examples of cancers that may be adenocarcinomas include lung, pancreatic, and colorectal types.
