High-risk cutaneous squamous cell carcinoma has the following characteristics: Diameter greater than or equal to 2 cm. Location on the ear, vermilion of the lip, central face, hands, feet, genitalia. Arising in elderly or immune suppressed patient.
The sun-exposed head and neck are the most frequent sites for these cancers to arise and in most patients diagnosed with a cutaneous squamous cell carcinoma, local treatment is usually curative.
Squamous cell and basal cell carcinoma occur more often in people who have more exposure to the sun or other sources of UV radiation over their lifetime.
What does SCC look like? SCCs can appear as scaly red patches, open sores, rough, thickened or wart-like skin, or raised growths with a central depression. At times, SCCs may crust over, itch or bleed. The lesions most commonly arise in sun-exposed areas of the body.
Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat. Check with your doctor if you have a lump or pain in your neck or throat that doesn't go away. These and other signs and symptoms may be caused by metastatic squamous neck cancer with occult primary.
Symptoms of stage 4 squamous cell carcinoma usually begin with some kind of skin lesion or growth. Often, the tumors of squamous cell carcinoma look like a scaly red patch of skin that won't heal. These tumors are often crusty and raised, and they may cause sores or ulcers that last for several weeks.
Metastasis of cutaneous squamous cell carcinoma (cSCC) is rare. However, certain tumor and patient characteristics increase the risk of metastasis. Prior studies have demonstrated metastasis rates of 3-9%, occurring, on average, one to two years after initial diagnosis [6].
Stage 1 squamous cell carcinoma
In stage 1, the cancer is less than 2 centimeters, about 4/5 of an inch across, has not spread to nearby lymph nodes or organs, and has one or fewer high-risk features.
The key warning signs are a new growth, a spot or bump that's getting larger over time, or a sore that doesn't heal within a few weeks. (See Signs and Symptoms of Basal and Squamous Cell Skin Cancer for a more detailed description of what to look for.)
They are of concern because of the similarity to squamous cell cancer. Squamous cell carcinoma is one of the three most common types of skin cancer. Basal cell, squamous cell, and melanoma. Squamous cell cancers can metastasize (spread) and should be removed surgically as soon as they are diagnosed.
In general, the squamous cell carcinoma survival rate is very high—when detected early, the five-year survival rate is 99 percent. Even if squamous cell carcinoma has spread to nearby lymph nodes, the cancer may be effectively treated through a combination of surgery and radiation treatment.
To lower your risk of getting skin cancer, you can protect your skin from UV rays from the sun, and avoid artificial sources of UV exposure like tanning beds and sunlamps.
Treatment should happen as soon as possible after diagnosis, since more advanced SCCs of the skin are more difficult to treat and can become dangerous, spreading to local lymph nodes, distant tissues and organs.
Patients with stage I, II, or III cancer have the best survival, whereas patients with stage IV or recurrent cancer who are older than 66.5 years have the worst survival.
Pulmonary metastases are the most frequent in SCC, accounting for 66% of distant metastases. It may be difficult to distinguish pulmonary metastasis from a new primary tumor, particularly if solitary. Other metastatic sites include bone (22%), liver (10%), skin, mediastinum and bone marrow.
Diagnosis of squamous cell carcinoma
Squamous cell carcinoma is most curable in the early stages before it spreads. If it's diagnosed early, the five-year survival rate is approximately 99%.
Most (95% to 98%) of squamous cell carcinomas can be cured if they are treated early. Once squamous cell carcinoma has spread beyond the skin, though, less than half of people live five years, even with aggressive treatment.
Age over 50: Most SCCs appear in people over age 50. Fair skin: People with fair skin are at an increased risk for SCC. Gender: Men are more likely to develop SCC. Sun-sensitive conditions including xeroderma pigmentosum.
Although squamous cell carcinoma can be more aggressive than basal cell cancer, the risk of this type of cancer spreading is low—as long as the cancer is treated early, Dr. Leffell says. He notes that the lesions must be treated with respect because they may grow rapidly and invade deeply.
Yes, squamous cell carcinoma can make you feel tired. It can make a person feel weak and exhausted. During the treatment procedures of squamous cell carcinoma, the patient tends to feel more tired. These types of fatigue that are related to cancer are known as cancer-related fatigue (CRF).
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.
Systemic chemotherapy is not widely used for treating squamous cell carcinoma. In most cases, the cancer cells are confined to one area of skin and, if detected early, can be effectively addressed with localized treatments, such as surgery.
SCCs can appear as thick, rough, scaly patches that may crust or bleed. They can also resemble warts, or open sores that don't completely heal. Sometimes SCCs show up as growths that are raised at the edges with a lower area in the center that may bleed or itch.
Most cases of squamous cell carcinoma can be cured when found early and treated properly. Today, many treatment options are available, and most are easily performed at a doctor's office.
