Remission is a medical term for when the signs and symptoms of a disease lessen significantly or disappear, sometimes for months, years, or even for life.

Basic meaning

In medicine, remission means:

  • The reduction or complete disappearance of disease symptoms.
  • It can describe both the change itself and the time period when the disease is quieter or inactive.

People often hear this word in the context of cancer, autoimmune diseases, and mental health conditions.

Partial vs. complete remission

Doctors usually talk about two main types:

  • Partial remission:
    • The disease is still present but has clearly decreased in severity.
* In cancer, this might mean a measurable tumor has shrunk by about half or more, and symptoms are improved.
  • Complete remission:
    • No detectable signs or symptoms of the disease remain on exams or tests.
* In cancer, scans and lab tests may show no evidence of active cancer cells.

Even in complete remission, some conditions still carry a risk that the disease can come back, which is called a relapse.

Remission vs. cured

Remission is not always the same as being cured.

  • Remission:
    • The disease is inactive or greatly reduced.
* There is still a possibility that it could return later.
  • Cured:
    • The disease is considered gone permanently, with no expected return.
* In cancer, some doctors may use “cured” only after many years (often 5 or more) with no signs of disease.

Because relapse is possible, many cancer specialists prefer phrases like “no evidence of disease (NED)” rather than “cured.”

How remission looks in different diseases

What “remission” means can vary depending on the condition.

  • Cancer:
    • Remission usually means tumors or cancer cells have shrunk or can’t be detected on scans or blood tests.
* This often follows treatments like surgery, chemotherapy, radiation, or immunotherapy.
  • Depression and other mental health conditions:
    • Remission is generally the absence of significant, impairing symptoms for a certain period (for example, at least 2 months for depression).
  • Autoimmune or inflammatory diseases (like rheumatoid arthritis):
    • Fewer swollen or tender joints, less pain, and lab tests that show reduced inflammation.

In all of these, remission marks a major improvement but still requires monitoring and follow-up.

Why remission matters emotionally

For many people, hearing “you’re in remission” is a huge psychological turning point.

  • It can bring relief, hope, and a sense of getting life back, even if fear of recurrence remains.
  • Patients and survivors often describe remission as a “new normal,” where they feel better but still stay alert to their health.

In online forums, people with cancer or chronic illness often say remission feels both like a victory and a fragile state, because they’re grateful to feel well but know things must still be watched.

Quick recap (TL;DR)

  • Remission = disease symptoms have reduced a lot or disappeared.
  • It can be partial (less disease) or complete (no detectable disease).
  • Remission is often different from being permanently cured, because the disease can sometimes return.
  • The exact definition depends on the condition (cancer, depression, arthritis, etc.), but it always signals a major improvement.
