Here are the 9 most common types of cancer
What Is The Survival Rate By Stage Of Melanoma?
Survival rates for melanoma can help provide a generic baseline for a person's outlook. However, several factors play a role in determining outcomes, and the condition will affect each person differently.
Melanoma is an aggressive form of skin cancer. After making a diagnosis, a doctor will provide more information about melanoma to their patient, potentially including the 5-year relative survival rate.
This article reviews the relative survival rates for melanoma and factors that can affect a person's outlook. It also looks at symptoms, diagnosis, treatment options, and more.
The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program collects data about melanoma incidence and relative survival rates. It breaks survival rates down based on stage, but it does not list the stages as 1 through 4.
SEER's 5-year relative survival rate breaks stages down as follows:
The 5-year relative survival rate for local melanoma is 99.6%, according to SEER.
The Melanoma Research Alliance states that the local stage includes both stages 0 and 2. It reports a survival rate of 98.4%. It is important to note that the overall survival rate is different from the relative survival rate.
RegionalAccording to SEER, the 5-year relative survival rate for regional melanoma is 73.9%.
SEER does not specify which numerical stages the "regional" classification includes, but the Melanoma Research Alliance notes that regional melanoma refers to stage 3.
The organization also reports a 5-year survival rate of 63.6%.
DistantDistant means the cancer has spread or metastasized to other areas of the body. It may refer to stage 4 melanoma.
According to SEER, the 5-year relative survival rate for distant melanoma is 35.1%. The Melanoma Research Alliance places the survival rate at 22.5%.
UnknownSEER also collects data on 5-year relative survival rate when the exact stage is not known. SEER instructs doctors to report a cancer stage as "unknown" if they lack sufficient data to stage the cancer.
According to SEER, the 5-year relative survival rate for melanoma when the stage is unknown is 92.6%.
Collecting dataA key feature of 5-year relative survival rates is where or when the data comes from.
SEER based the reported 5-year relative survival rates on data collected from 2013–2019.
The Melanoma Research Alliance did not specify what years it covers. However, it does note that the data is from 5–10 years ago.
Newer, potentially better treatments may exist today. This means that the survival rates may not reflect the latest treatment options available that may increase a person's chances of survival.
Several factors influence survival rates and a person's individual outcomes.
It is worth noting that survival rates are based on the stage of cancer when a person first receives the diagnosis, and they may be based on older, possibly less effective treatments.
Survival rates are not individualized. They do not represent a person's actual numbers and likelihood of survival.
The following factors can affect a person's outlook:
A person's doctor can provide them with more accurate information about their own outlook based on their individual circumstances.
Learn more about the outlook for those with skin cancer.
Early stages of melanoma may look like a mole. Other signs and symptoms can include:
It is best to contact a doctor if a person experiences symptoms of melanoma. The doctor will be able to order tests to confirm the diagnosis and then stage the cancer.
Learn more about melanoma symptoms.
A doctor will likely refer a person to a dermatologist for diagnosis if they suspect melanoma.
To diagnose the cancer, a dermatologist will:
A biopsy is typically necessary to confirm the diagnosis. This involves taking a sample of the affected skin for laboratory analysis.
If they find cancer, they will be able to tell how deep it is as well as how quickly it is developing. They may also be able to determine the stage.
Imaging tests can help with staging melanoma. These include:
A person's doctor can advise on which tests to order and what they involve.
Treatment for melanoma depends on several factors, including:
Where possible, doctors recommend surgical removal of the tumor.
People with more advanced stages may also require:
Learn more about treatments for melanoma.
In general, treatment focuses on removing the melanoma with surgery. Other treatments may help shrink the tumor and prevent it from growing or progressing to another stage.
Survival rates can provide a person with melanoma with some general information about their outlook. However, each person will have a different experience, and it is best to talk with a doctor for more information about what to expect after a diagnosis.
Melanoma may appear as an irregular-looking mole or growth. A person's doctor can advise on suitable treatments to remove the tumor and prevent it from growing.
A person who finds melanoma early — before it spreads — has the highest chance of survival. Treatment of early stages may only require surgery, but deeper or more advanced cases may require additional treatments.
Triple-negative Breast Cancer Survival And Recurrence Rates
Triple-negative breast cancer can spread faster and is more likely to recur than other types of breast cancer. With early diagnosis, the 5-year survival rate is 91%, but rates are lower for people whose cancer has spread.
If cancer has spread to distant parts of the body, the survival rate is much lower, around 12%.
Triple-negative breast cancer has lower survival rates than other breast cancers because it is more aggressive and difficult to treat.
Read more to learn about the survival rates for different stages of triple-negative breast cancer, its recurrence rates, and more.
If a person has triple-negative breast cancer, it means their cancer cells lack estrogen and progesterone receptors, and don't produce an abundance of the protein human epidermal growth factor receptor 2 (HER2).
Triple-negative breast cancer is more difficult to treat than other types of breast cancer and has high recurrence and metastasis rates.
Other breast cancers may have one or more receptor cells that respond to hormones or targeted agents. There are three main types:
Doctors diagnose breast cancer by identifying which receptors are present. They can treat it by targeting those receptors.
However, triple-negative breast cancer does not have any of these receptors. This means doctors cannot treat it by targeting specific receptors, making treatment options more limited.
Triple-negative breast cancer has higher recurrence rates than most other types of breast cancer, as follows:
Doctors consider triple-negative breast cancer more aggressive than other types of breast cancer.
The average time it takes this type of breast cancer to recur is 19–40 months, compared to 35–67 months for other types of breast cancer.
Therefore, doctors may recommend a mastectomy followed by radiation or chemotherapy. This treatment protocol can reduce an individual's risk of recurrence and improve their survival rate.
However, according to a 2021 study, cancer recurrence rates are the same for those who had lumpectomy or removal of a lump and mastectomy.
It indicated that a varied treatment protocol — including surgery, chemotherapy, and radiation — led to the best outcomes. As each person's cancer is different, a doctor or oncologist can determine which treatment options are best for an individual.
Triple-negative breast cancer accounted for about 12% of breast cancer diagnoses in the United States from 2012–2018. In general, it has a lower survival rate than other types of breast cancer.
How they are calculatedResearchers base survival rates on the percentage of people still alive at least 5 years after receiving a diagnosis.
The American Cancer Society (ACS) categorizes breast cancers into three groups based on if and how far they have spread:
According to the ACS, the 5-year survival rates for triple-negative breast cancer are:
Post-recurrence survivalA number of studies have found that if cancer recurs, the mortality rate within 3 months after the recurrence is as high as 75%.
That said, if the cancer does not recur within 5 years after the initial diagnosis, the rate of recurrence goes down to only 3%.
Survival rate limitationsCancer survival rates have some limitations. For example:
Certain people are more likely to develop triple-negative breast cancer. Some risk factors are unavoidable, while others are lifestyle-related.
People who are more likely to develop it include:
African Americans are twice as likely to get triple-negative breast cancer as their white counterparts. While scientists suspect genetics may play a role, experts also think inequities in healthcare, treatment options, and socioeconomic status contribute to their lower survival rates.
Hormone therapies are not effective in treating triple-negative breast cancer. Instead, doctors use other treatment methods.
A person's treatment protocol may include a combination of:
In addition, antibody-drug conjugate (ADC) is an emerging therapy that can be used for triple-negative breast cancer. It includes medications such as sacituzumab govitecan (Trodelvy) and trastuzumab deruxtecan (Enhertu).
Surgery may involve:
Although triple-negative breast cancer may be harder to treat than other breast cancers, this does not mean it is not treatable. Successful treatment depends on how early a doctor detects cancer and its stage at diagnosis.
Some people are more prone to triple-negative breast cancer than others. However, having risk factors does not necessarily mean that a person will develop the condition. Similarly, some people with no risk factors will develop it.
While it is impossible to prevent breast cancer, a person can reduce their risk by:
People should also have regular mammograms. The ACS recommends women aged 45–54 have annual mammograms. They also say females assigned at birth (FAAB) aged 40–44 should have the option to start having annual mammograms.
In addition, the U.S. Preventive Services Task Force (USPSTF) recommends that all FAABs start to get breast cancer screenings in their 40s.
Can you live 20 years after triple-negative breast cancer?It is not impossible to live for 20 years after triple-negative breast cancer. Given how aggressive this cancer can be, survival rates are lower in the first years after diagnosis. After 20 years, the survival rate may be around 83.7%.
That said, this study focused on women who have the BRCA2 gene and looked at a small sample size. There is limited data examining survival after 2 decades, likely because surviving for 20 years with triple-negative cancer is uncommon.
Can triple-negative breast cancer come back after 10 years?A 2018 Dutch population-based study found that the 10-year recurrence rate was 7.1%.
How often does triple-negative cancer come back?According to a 2019 study, about 40% of people living with stage 1 to stage 3 will have a recurrence after treatment.
Doctors consider triple-negative breast cancer aggressive. However, this does not mean that they cannot treat it.
This is why early diagnosis, regular mammograms, and self-exams are so important. The condition is easier to treat if found in its early stages, leading to a better outlook.
Survival rates depend greatly on the stage of cancer at diagnosis. Triple-negative breast cancer tends to recur more frequently than other types of cancer. However, if cancer does not return within 5 years, this risk decreases.

Light Rays Could Boost Cancer Survival Rate
Beams of light are the latest weapon in the battle against cancer, scientists announced today.
Photodynamic therapy, in which laser fibres are used to deliver light directly to a tumour, could boost survival rates of pancreatic cancer, research has found.
Pancreatic cancer is notoriously difficult to treat, largely because of the location of the pancreas close to major arteries and vital organs.
It is one of the top 10 leading causes of death from cancer worldwide, and kills about 6500 people in the UK every year.
Research published in the journal Gut shows that, for the first time, the light therapy increased the life expectancy of people with inoperable cancers by several months.
Researchers at University College London inserted up to six needles, carrying laser fibres, delivering light directly into the tumours of 16 patients with inoperable pancreatic cancer.
The treatment shrank the bulk of the tumour, which in most patients had been large, they found.
Almost half of the patients were still alive one year later; two survived two years; and one lived 30 months.
This is considerably better than would be expected as pancreatic cancer carries an average prognosis of six to 10 months, said lead researcher Professor Stephen Bown.
Only 10% of people are alive a year after the diagnosis has been made, he said.
Compared with chemotherapy or radiotherapy, which can incur debilitating side effects, patients were able to start eating and drinking within 48 hours, and they left hospital 10 days after their treatment, he said.
He added: "Photodynamic therapy may be useful for patients in whom surgery is not an option, and that it can be combined with chemotherapy and radiotherapy, if required.
"It certainly is one of the most difficult cancers to treat. It is early days for photodynamic therapy and it is not a cure, but the outcome so far offers a new approach to treating this unpleasant cancer.
"We hope that PDT can be combined with other therapeutic options and that in due course we may be able to improve the outlook for at least some of these unfortunate patients."
