Bob Marley and Melanoma: A Rare Skin Cancer That Isn't About the Sun
Reggae legend Bob Marley died in 1981 of acral lentiginous melanoma, a rare skin cancer that can appear on places like under a nail. Here's what melanoma is, from the National Cancer Institute.
A plain-language summary based on public reporting and trusted sources, linked below.

A dark spot under a toenail
Bob Marley was 36 when he died in a Miami hospital on May 11, 1981.
His official biography says the cancer started in his big toe in 1977, and that it came to light after a football injury. By September 1980 it had spread through his body, and he played the last concert of his career in Pittsburgh that month.
A 2025 paper in the Indian Journal of Dermatology, Venereology and Leprology, indexed in PubMed, is titled "Acral lentiginous melanoma and Bob Marley," and that is the diagnosis attached to his case in the medical literature. Melanoma is a cancer of melanocytes, the cells that give skin its color, and "acral" means the hands, the feet, and the nails. This page does not guess at anything the Marley family kept private, because the part worth your time is the medicine.
Why this kind of melanoma hides
Most melanoma is tied to ultraviolet light from the sun or from tanning beds. Acral lentiginous melanoma is not. StatPearls, the peer-reviewed reference on the NIH's NCBI Bookshelf, says UV radiation is not thought to play a significant part in how this subtype develops, and the tumors show up on skin that rarely sees the sun: palms, soles, and the skin under a nail.
The National Cancer Institute lists it as one of the main forms of melanoma, next to the superficial spreading and nodular types.
The location is what makes it dangerous. A dark streak under a nail looks like a bruise, and a dark patch on a sole looks like a callus or a stain, so people wait.
NCI is blunt about who gets melanoma: fair skin raises the risk, but anyone can get it, including people with dark skin.
The signs, in five letters
NCI teaches the warning signs with the letters ABCDE:
- Asymmetry. Split the spot in half. The two halves do not match.
- Border. The edge is ragged or hard to trace.
- Color. More than one color sits in the same spot.
- Diameter. Melanoma is usually wider than 6 millimeters.
- Evolving. It changes in size, shape, or color over time.
When to get it checked
NCI says to call a doctor about a mole that changes in size, shape, or color. The same goes for a mole with ragged edges, a mole with more than one color, or a mole whose two halves do not match.
Other reasons to book a visit, per NCI:
- The spot itches, oozes, or bleeds.
- It has ulcerated. That means the top layer of skin has broken down and the tissue below shows through.
- New moles have grown right next to an older one. NCI calls these satellite moles.
- An area of colored skin has changed.
Because of where acral melanoma grows, add your palms, soles, and nail beds to the check. A new dark band under a nail is worth a look, even with no pain.
How doctors find out
The test is a biopsy. That means taking cells or tissue so a pathologist can view them under a microscope. NCI describes four main types. A shave biopsy shaves off the growth, and a punch biopsy uses a hollow circular tool to cut out a small round core. An incisional biopsy cuts out part of the growth, while an excisional biopsy takes the whole thing.
NCI notes that an early melanoma can be hard to tell from an ordinary mole, so patients may ask for a second pathologist to read the sample. The tissue may also be tested for gene changes that help plan treatment.
Stage comes next, and our guide to cancer staging covers the general idea. For melanoma, NCI says the stage rests on how thick the tumor is, whether the skin over it has broken open, and whether cancer has reached lymph nodes or other organs. Thickness is measured from the skin surface down to the deepest cancer cell.
Stage 0 means the abnormal melanocytes sit only in the epidermis, the outer layer, and is also called melanoma in situ. In stage IA the tumor is no more than 1 millimeter thick, and in stage IB it is 1 to 2 millimeters thick without a break in the skin.
To check the nodes, surgeons use sentinel lymph node biopsy. A dye or tracer is injected near the tumor and drains to the first node in line. That node is removed and examined, and if it is clear, more nodes often stay put.
What treatment involves
Surgery is the base. NCI says stage I melanoma is usually treated by cutting out the tumor plus a rim of normal tissue, with or without a sentinel node biopsy. If the sentinel node holds cancer, more nodes may be removed. When only a few cancer cells turn up in that node, NCI notes that watching with ultrasound may replace more surgery.
For melanoma that has spread, drug treatment carries the weight. Our overview of immunotherapy explains the class of drugs that now anchors advanced disease. NCI's health-professional summary adds a note specific to acral and mucosal melanoma: some carry changes in a gene called KIT, and early data suggest those tumors may respond to c-KIT inhibitor drugs. Trials are open for people with a KIT change and stage III or IV disease.
When melanoma reaches distant organs, it is called metastatic cancer.
The numbers, and who they describe
The American Cancer Society projects about 112,000 new melanoma cases in the United States in 2026 and about 8,510 deaths; the federal SEER registry publishes those projections alongside its own data. Five-year relative survival across all stages was 94.7% for people diagnosed from 2016 through 2022.
Stage at diagnosis drives that figure. Across the same 2016–2022 group, SEER finds 77% of melanoma while still local, and five-year relative survival there is 100.0%. Ten percent is found in nearby lymph nodes, at 76.0%. Five percent is found after it has spread to distant sites, at 34.0%. Nine percent is not staged.
These are group averages drawn from thousands of past patients. They describe a population, not one person's course.
What this does not mean
Marley was treated in 1980 and 1981, and melanoma care has changed a great deal since then. His outcome says nothing about anyone treated today.
A famous case also cannot set your own risk, and it cannot tell you whether a spot on your foot is anything at all.
Most dark spots are not cancer. The point of knowing the signs is not fear, but that a spot in an odd place still deserves a real look.

Put the story in context
Prevention, possible warning signs, screening, and diagnosis
This story relates to Melanoma / skin cancer. The information below is general: it does not reveal anything else about a public person’s health, and not every point applies to every cancer. Personal advice depends on age, symptoms, family history, exposures, and medical history.
Prevention and risk reduction
Not every cancer can be prevented. Avoiding tobacco, protecting skin from ultraviolet radiation, limiting alcohol, staying active, and receiving recommended HPV or hepatitis B vaccination can lower the risk of certain cancers. A risk factor is not a prediction or a cause in one individual.
Symptoms and possible early signs
Possible signs vary and are often caused by conditions other than cancer. Changes worth discussing include a new lump, unexplained bleeding or weight loss, a persistent cough, lasting bowel or bladder changes, a changing skin spot, or symptoms that persist or worsen. Some early cancers cause no symptoms.
Screening and early detection
Screening looks for certain cancers before symptoms begin. Recommended tests exist only for some cancers and depend on age and risk. Screening can have benefits and harms; it is not the same as evaluating a new symptom, and there is no single routine scan or blood test that reliably screens for every cancer.
How cancer is diagnosed
Diagnosis may involve a history and exam, imaging, laboratory tests, and often a biopsy. Pathology can identify the cancer type and may test biomarkers that guide treatment. Symptoms, screening results, tumor markers, or online stories alone cannot confirm cancer.
