Is Any Stage IV Cancer Curable?

Breast cancer

According to the American Cancer Society, patients whose breast cancer is detected while it is still in the localized form have a 5-year survival rate of 98%. However, patients with stages III and IV breast cancer have survival rates of 72% and 26%, respectively.

Melanoma

Skin cancer is the most common form of all types of cancer, and if found early, nearly 100% treatable, according to the American Academy of Dermatology. The 5-year survival rate of patients with stage IV melanoma, however, is around 19%.

Prostate cancer

Prostate cancer is one of the most common types of cancer in men. According to the Surveillance, Epidemiology and End Results (SEER) Program, the 5-year survival rate is 98.9% if the cancer is caught before it has spread beyond the prostate gland. The survival rate drops to about 28-30% if the cancer is detected at stage IV.

Colon cancer

Also known as colorectal or bowel cancer, colon cancer is the third most common cancer among men and women according to the Centers for Disease Control and Prevention (CDC). It is also the second most common cause of cancer-related deaths in the U.S. because it is often not diagnosed early enough. The 5-year survival rate for stage IV colon cancer is 39%. For stage IV rectal cancer, the 5-year survival rate is 12%.

Testicular cancer

Most often found in young men between the ages of 15-45, testicular cancer is treatable 99.2% of the time when it is detected early. However, only 73.1% of patients are cancer-free after five years if their cancer is diagnosed after it has spread, especially in stage IV.

Cervical cancer

Occurring in the cells of the cervix, cervical cancer is slow-growing. Detecting cervical cancer while the lesions are precancerous leads to a near 100% survival rate according to the American Cancer Society. However, this rate drops to just 32% if the cancer is diagnosed in stage III, and 15-16% if diagnosed in stage IV.

Lung cancer

Usually considered a very deadly cancer, lung cancer has a less than 5% survival rate if diagnosed in stage IV.

Pancreatic cancer

Stage IV pancreatic cancer has a survival rate of 1% over five years. An average patient diagnosed with late-stage pancreatic cancer will live for about one year.

Treatment for stage IV depends on the location of the cancer and the organs involved. The more widely the cancer has spread from the site where it was first diagnosed, the more difficult it becomes to treat. Patients diagnosed with stage IV or metastatic cancer may not survive long without treatment. 

Options to treat stage IV cancer may involve chemotherapy, radiation therapy, biological therapy, hormone therapy or surgery, or a combination of these modalities. 

While chemotherapy can often kill a small number of cancer cells, it is usually less effective in eradicating a larger number of tumor cells present in widespread metastases. If the cancer has spread to only a few small areas, surgeons may be able to remove it to prolong the patient’s survival.

In most cases, treatment of stage IV cancer is aimed at prolonging patients’ survival and improving their quality of life. 

Advances in the field of medicine, especially in cancer research and technology in the last two decades, have shown that there is hope for the future.

Each year, new data emerges from a scope of technology that is ever-expanding and helping to provide patients with a new lease on life. However, like any new information, it’s important to evaluate it judiciously and be realistic about what is possible. 

It’s also important to remember that there is still life after a cancer diagnosis, even if it is in stage IV.
