Surgery might be preferable in a few specific situations:
- Very large or invasive tumors: If a skin cancer is quite large (for instance, spanning several centimeters) or has grown deeply into the skin or underlying tissue, surgery may be more practical to ensure complete removal. Radiation can treat large areas too, but the bigger the field, the more side effects and the more sessions required – at some point, surgery might clear it faster and with known margins.
- Certain aggressive subtypes: If a tumor has features like perineural invasion (cancer cells tracking along nerves) or is an aggressive squamous cell carcinoma at risk for spread, doctors often favor surgery (sometimes combined with radiation after) to get clear margins and possibly examine lymph nodes. Mohs surgery in particular can trace out roots of a morpheaform basal cell very well; while IG-SRT can still cure it, some dermatologists might feel more secure having pathology in hand for those aggressive subtypes.
- Need for immediate results or pathology: Some patients or situations require knowing immediately that the cancer is out. For example, if the diagnosis is uncertain or there’s a possibility something more is going on, a surgical excision with pathology gives answers quickly. Or if the patient cannot return for multiple visits (though in that case, sometimes radiation would be worse due to the time required – so surgery one-and-done might be better for those with limited ability to attend).
- Recurrent tumors after radiation: If a tumor (rarely) comes back after IG-SRT or was previously radiated, surgery is usually the go-to for the recurrence, because you generally wouldn’t radiate the exact same area twice at full dose.
- Patient factors: Some people might not want to commit to the many visits for IG-SRT or might have concerns about radiation. If a patient says, “I’d rather just get it over with in one shot,” then surgery could be the better option for that individual’s peace of mind, assuming they’re medically fit for it.
- Melanoma or other non-indicated cancers: As noted, melanoma requires surgery – IG-SRT isn’t an option there. So if there was any ambiguity or mixed lesion (like part of it is invasive melanoma, etc.), then surgery is mandatory.
- Previous radiation in the area: If the area has already had a full radiation dose, surgery would be chosen for a new cancer in that scar because you can’t re-radiate at full dose usually.
In summary, surgery might be better for very large, aggressive, or previously radiated cancers, or when immediate margin confirmation is critical. Mohs surgery is excellent for getting all roots out in one day, so for complex or high-risk tumors, some doctors lean that way. However, for the typical small to moderate basal or squamous cell carcinoma, surgery is not “better” per se than IG-SRT – it’s more about patient preference. We will guide you if we feel a particular case truly warrants surgery first. But often it’s a matter of weighing pros and cons rather than a clear-cut “this is better.” Ultimately, if surgery is strongly recommended by the dermatologist, it’s because in their judgment that scenario would achieve the best outcome with surgery. But in many cases, IG-SRT could still be an alternative if one understands the trade-offs. It’s always a personalized decision.
