Squamous Cell Skin Cancer

What is squamous cell skin cancer?

Each year in the United States, as many as 5.4 million basal and squamous cell carcinomas are diagnosed in nearly 3.3 million people (many have more than one), making it a very common form of cancer. Approximately two out of 10 skin cancers are squamous cell carcinomas, which develop in the flat squamous cells that are found on the outer layers of your skin.

This type of cancer is largely associated with exposure to the sun’s ultraviolet rays, so they develop in areas that see the most sun, namely your:

  • Face
  • Ears
  • Hands
  • Neck
  • Lips


Squamous cell skin cancer is more likely to spread than its cousin, basal cell carcinoma, but this still doesn’t happen often.

What are the signs of squamous cell skin cancer?

The most common signs of squamous cell carcinoma are:

  • A protruding red nodule on your skin
  • A sore on old scar tissue
  • A sore or patch that doesn’t heal
  • A scaly, red patch on your skin


You know your body best, so if you have a spot on your skin that seems out of the ordinary and is slow to go away or doesn’t respond to conventional treatments, it’s best to have Dr. Fischer take a look.

How is squamous cell skin cancer diagnosed?

If you have a suspicious lump or patch of skin, Dr. Fischer first performs a biopsy to make a diagnosis. If cancer cells are present, Dr. Fischer then removes it using an approach that excises the abnormal cells, as well as a margin of healthy skin surrounding the area.Dr. Fischer ensures that he removes enough tissue to fully encompass the potentially affected area.Next, Dr. Fischer and a team of experienced pathologists studies the excised tissue to determine how extensive it is.

In certain instances, he may want to rule out, or confirm, the spread of your squamous cell cancer, he performs a sentinel lymph node biopsy. To do this, he injects a dye into an area close to where he identified your skin cancer and follows the dye to the nearest lymph node, which becomes the sentinel lymph node.

Once located, he removes your sentinel lymph node for further study. It’s worth mentioning that squamous cell skin cancer doesn’t spread often and these steps are largely precautionary. If, however, he does find cancer cells in your lymph node, these minimally invasive measures warrant the effort.
