5 treatment settings, 4 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.
Excision with margin control or Mohs surgery, nodal evaluation, and postoperative radiotherapy for perineural invasion, positive margins or nodal disease; neoadjuvant cemiplimab to shrink large tumours before surgery.
IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.
A PD-1 blocker that is the standard for advanced skin squamous cell carcinoma, and in 2025 became the first adjuvant immunotherapy for it.
Removing just the first lymph node a tumour drains to, instead of all of them, to check for spread.

Cemiplimab (EMPOWER-CSCC-1), pembrolizumab (KEYNOTE-629) or cosibelimab; radiotherapy for symptomatic sites.
A PD-1 blocker that is the standard for advanced skin squamous cell carcinoma, and in 2025 became the first adjuvant immunotherapy for it.
Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.
Cosibelimab is a PD-L1 antibody approved in December 2024 for advanced cutaneous squamous cell carcinoma, offering a third immunotherapy choice.
IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.
Objective response 47% in the metastatic group; 46% in the pooled analysis of 193 patients with 16% complete responses.
Objective response 34% in recurrent or metastatic disease and 50% in locally advanced disease.

Cetuximab with or without radiotherapy, platinum-based chemotherapy, capecitabine; clinical trials of RP1 with cemiplimab or photoimmunotherapy.
Cetuximab is a chimeric antibody that blocks the EGFR growth receptor. It is used with FOLFIRI or FOLFOX in RAS wild-type, left-sided bowel cancer, with encorafenib in BRAF V600E disease, with KRAS G12C inhibitors, and with radiation or chemotherapy in head and neck cancer; RAS-mutant tumours gain nothing and may be harmed, so RAS testing comes first.
Carboplatin is a platinum chemotherapy that crosslinks DNA; it is part of the standard pre-surgery regimen for triple-negative breast cancer.
Vusolimogene oderparepvec is an engineered herpes virus injected into melanoma tumours, approved in August 2026 with nivolumab after immunotherapy failure.

Reduce immunosuppression and switch to sirolimus or everolimus where possible; PD-1 blockade only after weighing graft rejection risk; surgery and radiotherapy preferred.
An mTOR-blocking pill that doubled progression-free time with exemestane in 2012 and is now paired with the oral SERD giredestrant.
A PD-1 blocker that is the standard for advanced skin squamous cell carcinoma, and in 2025 became the first adjuvant immunotherapy for it.
