If you have skin cancer, what happens next depends almost entirely on the type and how early it’s caught. Most skin cancers are highly treatable when found early, and the process typically follows a predictable path: a suspicious spot is noticed, a biopsy confirms (or rules out) cancer, and treatment removes the affected tissue. For the most common types, the entire process can be handled in an outpatient visit. For melanoma or advanced cases, the road is longer and more involved.
The Three Main Types and What They Look Like
Not all skin cancers behave the same way. Basal cell carcinoma is the most common and slowest growing. On lighter skin, it typically appears as a skin-colored or pink bump. On darker skin, it often looks like a brown or glossy black bump with a rolled border. It almost always shows up on sun-exposed areas like the face.
Squamous cell carcinoma is the second most common type. It tends to develop on the lower lip, ears, and other areas that get consistent sun exposure. It can look like a rough, scaly patch or a firm red bump that doesn’t go away.
Melanoma is the least common but most dangerous. The first sign is often a mole that changes in size, shape, or color. Irregular borders and multiple colors within a single spot are classic warning signs. While basal and squamous cell cancers rarely spread to other parts of the body, melanoma can, which is why catching it early matters so much.
General signs that apply across all types include a new growth that looks like a mole, bump, or scab; a sore that won’t heal; changes to an existing mole or freckle; or itching and pain around a skin growth.
How Skin Cancer Is Confirmed
A doctor can’t diagnose skin cancer just by looking at it. If a spot looks suspicious, the next step is a biopsy, where a small sample of skin is removed and examined under a microscope. The area is cleaned, numbed with a local anesthetic, and then sampled using one of a few techniques.
A shave biopsy uses a razor to remove a thin surface layer of skin. It’s the least invasive option and doesn’t require stitches. A punch biopsy uses a small circular tool to take a deeper, round sample, and usually needs a stitch or two. An excisional biopsy uses a scalpel to remove a larger piece of skin, also closed with stitches. Your doctor chooses the method based on the size, depth, and location of the spot.
Results typically come back within a week or two. If cancer is confirmed, the pathology report will identify the type of skin cancer, how deep it goes, and whether the edges of the sample are clear of cancer cells. This information determines what happens next.
Treatment for Early-Stage Skin Cancer
For basal and squamous cell carcinomas caught early, treatment is usually straightforward. The most common approach is surgical removal, where the cancerous tissue and a margin of healthy skin around it are cut out. For small, surface-level cancers, freezing the tissue with liquid nitrogen (cryotherapy) is another option. A scab forms and peels away on its own within one to three weeks.
For skin cancers on the face, scalp, ears, hands, feet, or other areas where preserving healthy tissue matters, a specialized technique called Mohs surgery is the gold standard. During this procedure, the surgeon removes one thin layer of tissue at a time, examining each layer under a microscope before deciding whether to take more. This continues until no cancer cells remain. The advantage is precision: only cancerous tissue is removed, sparing as much healthy skin as possible. Cure rates for new basal cell carcinomas reach up to 99%, and squamous cell carcinomas are cured at rates between 95% and 99%.
Even for cancers that have come back after previous treatment, Mohs surgery still achieves cure rates of 90% to 94%.
What Recovery Looks Like
After surgical removal, recovery is relatively simple for most people. You’ll be sent home the same day with wound care instructions. Keeping the wound clean, changing dressings, and limiting strenuous activity to prevent the wound from reopening are the main priorities. If stitches were placed, they’re typically removed within one to two weeks.
Some scarring is normal. Proper wound care during healing reduces the likelihood of a noticeable scar, though the final appearance depends on the size and location of the excision. Skin on the face tends to heal well, while areas that stretch or move a lot may take longer.
When Skin Cancer Has Spread
Melanoma that isn’t caught early can spread to other parts of the body, most commonly the lymph nodes, brain, bones, liver, or lungs. The symptoms at this stage depend on where the cancer has traveled. Melanoma that reaches the lungs can cause a persistent cough or shortness of breath. In the brain, it may cause headaches or seizures. Spread to the liver often shows up as unexplained weight loss or loss of appetite, while bone involvement can cause deep pain or unusual fractures. Swollen lymph nodes, particularly near the original cancer site, are another common sign.
Advanced squamous cell carcinoma can also spread, though it does so far less frequently than melanoma. Basal cell carcinoma almost never metastasizes, though if left untreated for a long time, it can grow into surrounding tissue and cause significant local damage.
Treatment for Advanced Cases
When skin cancer has spread beyond the original site, treatment goes beyond surgery. Two main approaches have transformed outcomes over the past decade.
Immunotherapy works by helping your immune system recognize and attack cancer cells it would otherwise miss. These treatments are given as infusions, typically every few weeks, and can produce durable responses, meaning the cancer stays controlled for years in some patients. Side effects vary but can include fatigue, skin reactions, and inflammation in various organs as the immune system becomes more active.
Targeted therapy works differently. About half of melanomas have a specific genetic mutation that drives the cancer’s growth. Drugs designed to block that mutation can shrink tumors rapidly. These are usually taken as daily pills. The response can be dramatic, though some cancers eventually find ways to grow again, which is why targeted therapy is sometimes combined with immunotherapy.
Radiation therapy is also used in some cases, particularly when surgery isn’t feasible or as a follow-up to reduce the chance of recurrence.
Survival Rates by Stage
The numbers paint a clear picture of why early detection matters. For melanoma that’s still localized (confined to the skin where it started), the five-year survival rate is greater than 99%. Once it spreads to nearby lymph nodes (regional spread), that drops to 76%. For melanoma that has reached distant organs, the five-year survival rate is 35%, based on data from patients diagnosed between 2015 and 2021.
Those distant-stage numbers have actually improved significantly in recent years thanks to immunotherapy and targeted treatments that didn’t exist a decade ago. For basal and squamous cell carcinomas, survival rates are even higher across the board, since these cancers rarely spread in the first place.
Long-Term Monitoring After Treatment
Having skin cancer once increases your risk of developing it again, either as a recurrence in the same spot or as an entirely new cancer elsewhere on your body. Follow-up schedules are based on how advanced the original cancer was.
For very early melanoma (stage 0, also called melanoma in situ), annual skin checks are sufficient. For low-risk melanoma that was caught early, follow-up visits every 6 to 12 months are typical. Higher-risk cases, where the melanoma was thicker or had started to spread, call for visits every 3 to 6 months, particularly in the first few years when recurrence is most likely.
European and American guidelines recommend stage-specific monitoring for at least 5 years to watch for recurrence, and continued skin checks for at least 10 years to catch new skin cancers. Many dermatologists recommend lifelong annual skin exams for anyone who has had a previous skin cancer diagnosis. Between visits, checking your own skin monthly for new or changing spots is one of the most effective things you can do.
