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.
Skin cancer on the scalp may look like a mole, an ulcer, a sore, or another type of growth. Growths on the scalp can change in shape, color, or size and may itch or bleed, which may be concerning for skin cancer. Treatment for skin cancer depends on the type and severity of the cancer.
Diagnosis of squamous cell carcinoma
If any sores, bumps or lesions are found, your doctor may order a biopsy of the tissue to test it for cancerous cells. 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%.
Squamous cell carcinoma (SCC) of the scalp is the second most common non-melanoma cancer of the skin. The incidence of squamous cell carcinoma on the scalp is on the rise, but the intracranial extension is rare. Cranial invasion is rare in SCC of the scalp, but when present, it is associated with a poor prognosis.

Using a scalpel, the surgeon removes the entire tumor along with a “safety margin” of surrounding normal tissue. The margin of normal skin removed depends on the thickness and location of the tumor. Typically, the patient goes home after the surgery, and the excised tumor goes to the lab.
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].
However, a subset is diagnosed with a high-risk cutaneous squamous cell carcinoma. High-risk factors include size (>2 cm), thickness/depth of invasion (>4 mm), recurrent lesions, the presence of perineural invasion, location near the parotid gland, and immunosuppression.
Basal cell skin cancer (BCC): looks like a pink spot that can be flat or raised. Like BCCs in other areas, they can bleed easily, even with minor injury. Larger cancers may even have visible irregular blood vessels on its surface, and varies from being shiny to rough and crusty.
What are the symptoms of skin cancer of the head and neck? Skin cancers usually present as an abnormal growth on the skin. The growth may have the appearance of a wart, crusty spot, ulcer, mole or sore. It may or may not bleed and can be painful.
Malignant skin tumours of the scalp with skull invasion, dural infiltration and brain involvement are uncommon. However, in advanced cases, skin cancer may be associated with infiltration of the skull bone and even the brain.
The highest quartile patients reported >18 months between noticing the lesion and removal, defined as long total delay. 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.
Squamous cell carcinoma on the scalp can readily penetrate the full thickness of the cranium and invade the dura mater, sagittal sinus and brain. We suggest wide resection of the scalp and split thickness skin graft with sentinel lymph node biopsy, following by postoperative radiation therapy.
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.
Squamous Cell Carcinoma Early Stages
At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface.
Untreated squamous cell carcinoma of the skin can destroy nearby healthy tissue, spread to the lymph nodes or other organs, and may be fatal, although this is uncommon.
Death from basal and squamous cell skin cancers is uncommon. It's thought that about 2,000 people in the US die each year from these cancers, and that this rate has been dropping in recent years.
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).
If squamous cell carcinoma has spread, chemo might be an option, although an immunotherapy drug might be used first. If chemo is used, drugs such as cisplatin and 5-fluorouracil (5-FU) might be options. These drugs are given into a vein (intravenously, or IV), usually once every few weeks.
This topic last updated: Jul 05, 2023. The prognosis of patients with recurrent or metastatic head and neck squamous cell cancer is generally poor. The median survival in most series is 6 to 15 months depending on patient- and disease-related factors.
Immunotherapy (updated 12/2022)
Currently, there are 2 immunotherapy drugs approved by the U.S. Food and Drug Administration (FDA) to treat recurrent or metastatic head and neck squamous cell carcinoma: Pembrolizumab (Keytruda).
The recommended treatment for cutaneous squamous cell cancer (CuSCC) of the head and neck is Mohs surgical excision or wide local excision. Excision is recommended to a gross surgical margin of 4–6 mm however this is based on limited evidence and specify a goal histologic margin.
