When cancer spreads to distant organs, tissue, or lymph nodes, it is classified as stage 4 breast cancer. Stage 4 breast cancer is often known as advanced cancer, secondary breast cancer, or metastatic breast cancer by healthcare experts.

Symptoms differ depending on where the cancer has spread. Treatment for stage 4 breast cancer attempts to keep the cancer under control, reduce symptoms, and provide the best possible quality of life for the patient.

This article goes through the signs and symptoms of stage 4 breast cancer, as well as the outlook and treatment choices.

Stage 4 breast cancer

Stage 4 breast cancer

Stage 4 breast cancer develops when cancerous cells migrate beyond the breast and nearby lymph nodes to other parts of the body.

Breast cancer most usually spreads to the lungs, liver, and bones, according to the American Cancer Society (ACS). It can potentially spread to other organs like as lymph nodes, skin, and the brain.

Stage 4 breast cancer can be diagnosed as either a new case (de novo) or a recurrence of a previous case (recurrence).

Rates of survival

The Surveillance, Epidemiology, and End Results (SEER) Program database is used by the American Cancer Society to track 5-year relative survival rates.

A relative survival rate estimates how long a person with a certain ailment will survive after obtaining a diagnosis in comparison to those who do not have the condition.

If the 5-year relative survival rate is 70%, it signifies that a person with the ailment has a 70% chance of living for 5 years as someone who does not have the condition.

According to the American Cancer Society, the 5-year relative survival rate for stage 4 breast cancer is 28% for women and 22% for men.

The type of breast cancer a person has can also affect the 5-year relative survival rate. For example, the 5-year survival rate for a person with triple-negative breast cancer is 12%, and it is 19% for those with inflammatory breast cancer.

According to the American Cancer Society, survival statistics are dependent on a number of criteria but do not account for every facet of a person’s health and well-being.

The following are some aspects that survival rates do not consider:

  • the person’s age and overall health
  • the size of the tumor
  • the cancer’s response to treatment
  • the cancer’s HER2 status
  • the presence of hormone receptors on cancer cells
  • new treatment options that improve the long-term outlook

As a result, it’s essential to keep in mind that these figures are estimations. A person might inquire about how their disease is going to effect them from a healthcare practitioner.

Is it treatable?

Experts consider stage 4 breast cancer to be incurable, according to a 2016 report. Treatments, on the other hand, can assist to relieve symptoms, decrease the tumor, and extend survival time.

A person with stage 4 breast cancer should consult with a specialist to discover the best therapy choices for them.

  • slow down and control the growth of the cancer

When cancer goes into remission, tests that seek for cancer cannot detect it. A doctor may refer to this pathological complete response.

Treatment may also produce partial remission. This suggests that therapy has destroyed a portion of the cancer but that testing can still discover the cancer.

Stage 4 breast cancer will not go away completely. However, states that therapy can help manage the cancer for years. It states that the cancer might be aggressive at times and go into remission at other times.
