Cancer is a devastating disease that can affect nearly any part of the body. When cells grow out of control, they can form malignant tumors that can spread to other areas. Cancer remains one of the leading causes of death worldwide. However, not all cancers share the same prognosis. Advances in screening, diagnosis and treatment have led to improved survival rates for many types of cancer. Some cancers, when caught early, have five-year survival rates of over 90 percent. Let’s explore some of the most survivable cancers.
What Factors Affect Cancer Survival Rates?
Survival rates for cancer refer to the percentage of patients who live for at least five years after being diagnosed. However, many factors influence these statistics, including:
- Type of cancer – Some cancer types are inherently more aggressive or fast-growing than others. Prostate cancer tends to be slow growing compared to pancreatic cancer, for example.
- Stage at diagnosis – Cancers found at an early stage when localized to one area are more treatable than later stage cancers that have spread.
- Age – Younger people often have higher survival rates for the same cancer type as older individuals.
- Overall health – Patients in good health and with strong immune systems tend to respond better to treatment.
- Access to treatment – Survival is impacted by the availability of screening services and new therapies.
With these caveats, let’s look at cancers with the highest five-year relative survival rates.

Cancers with the Highest 5-Year Survival Rates
5-year relative survival rate: 95%
Testicular cancer begins in the testicles, which are part of the male reproductive system. This cancer most often affects men between ages 20 and 54. Thanks to effective treatments, testicular cancer has one of the highest five-year survival rates of all cancers. In the United States, the overall five-year survival rate is 95 percent. If caught before the cancer has spread, the survival rate is 99 percent.
Men should check themselves regularly for any unusual lumps or swelling. Testicular cancer has high cure rates, especially when treated before metastasis. Surgery is often sufficient, sometimes combined with chemotherapy or radiation.
5-year relative survival rate: 98%
Thyroid cancer starts in the thyroid gland, which is located in the front of the neck and produces hormones. Thyroid cancer is among the least deadly cancers with a five-year relative survival rate of 98 percent.
Overdiagnosis may artificially inflate the survival rate, as many thyroid tumors remain small and don’t become cancerous. However, even discounting overdiagnosis, thyroid cancer has an excellent prognosis when found early. For localized thyroid cancers, the five-year survival rate reaches 100 percent.
Surgery is the standard treatment and often cures thyroid cancer as long as it hasn’t spread beyond the neck. Radioactive iodine therapy post-surgery helps destroy any remaining cancer cells.
5-year relative survival rate: 97%
The prostate is a small gland in men that produces some fluids found in semen. Prostate cancer usually grows slowly, so most men can live many years even without treatment. However, in some cases the cancer grows and spreads quickly.
Overall, the five-year relative survival rate for prostate cancer is 97 percent. Localized prostate cancer confined to the prostate has nearly a 100 percent five-year survival. If the cancer spreads to distant parts of the body, the survival rate drops to 30 percent.
Early prostate cancer usually has no symptoms. Testing for prostate-specific antigen (PSA) levels can detect cancer before it spreads. Treatments for prostate cancer include surgery, radiation therapy, and hormone therapy.
5-year relative survival rate: 92%
Melanoma is a serious type of skin cancer that begins in melanocytes, which create skin pigment. Catching melanoma early is crucial, as the cancer can quickly spread to other organs. When detected at an early stage, the five-year survival rate is 99 percent. This drops to 25 percent once the melanoma has spread to distant areas.
Preventing sunburns and tanning bed use can help avoid melanoma. Look for any new or changing moles to spot melanoma early when it is highly treatable. Standard treatment is excisional surgery to remove the tumor and some surrounding normal skin.
5-year relative survival rate: 90%
Breast cancer originates in breast tissues and can occur in both women and men. Thanks to better screening and treatments, survival rates are improving. The current overall five-year relative survival rate for breast cancer is 90 percent. For localized breast cancer, the five-year survival rate is 99 percent.
Annual mammograms can detect tumors early, sometimes up to three years before they can be felt. Breast self-exams also help women notice any changes. Common treatments include surgery, radiation, chemotherapy, and hormone therapy.
5-year relative survival rate: 86%
Hodgkin lymphoma affects the body’s infection-fighting lymph nodes. It spreads in an orderly manner from one group of lymph nodes to the next. This type of cancer is rare, accounting for less than one percent of all cancers in the United States.
The five-year relative survival rate for Hodgkin lymphoma is 86 percent. If caught early before spreading, patients have a five-year survival rate of 92 percent. Advances in radiation and chemotherapy have improved prognosis tremendously in recent decades.
Patients often notice painless lymph node swelling in the neck, underarm, or groin area. Treatments include chemotherapy, radiation therapy, and stem cell transplants.
Promising Advances Against Cancer
Researchers are making progress in understanding and treating cancer. New technologies are improving screening, diagnosis and therapies. Some key areas of advancement include:
- Immunotherapy – These treatments boost the body’s immune system to help fight cancer. Checkpoint inhibitors are one type that block proteins on cancer cells.
- Targeted therapy – These drugs specifically attack cancer cells while causing less damage to normal cells compared to chemotherapy.
- Precision medicine – By analyzing genetics and biomarkers, doctors can select treatments most likely to work for each patient.
- PARP inhibitors – This targeted therapy blocks repair of cancer cell DNA, killing those cells. It benefits patients with BRCA gene mutations.
- Proton therapy – This precisely targeted radiation therapy minimizes damage to tissues around a tumor.
Research and clinical trials remain critical to finding new cures and improving survival rates. Patients should discuss all treatment options with their cancer care team. While preventative health measures can reduce cancer risk, advances in cancer treatments offer new hope.

Cancer survival rates vary greatly depending on multiple factors. Testicular, thyroid, prostate, and skin cancers often have higher survival odds when diagnosed and treated early. Other cancers like breast cancer and Hodgkin lymphoma also have relatively high survival rates, especially when localized. However, any cancer can be potentially deadly once it metastasizes and spreads throughout the body. Therefore, regular screening and knowing the common signs of cancer are extremely important. New immunotherapies, targeted drugs, genetic testing, and enhanced radiation therapies are also improving prognosis. While cancer remains a devastating illness, the outlook is hopeful thanks to medical progress. Patients should learn about prevention, get screened appropriately, and seek prompt treatment when cancers are most curable.
