We always expect our cancer treatment to go well and to heal quickly. But sometimes our body doesn’t respond the way we want. Recurrence and progression may sound equally dangerous, but they are not the same. 

What is cancer recurrence?

Cancer recurrence is the return of cancer after a period of remission. This means your treatment was called successful, as no signs of cancer were detected, but then it showed again. Recurrence can happen in the same location or in the nearby tissues of your body. At this point, you may feel your treatment failed because the cancer is back. But it just means a few cancer cells stayed back, and now they have started growing again.

What is cancer progression?

Cancer progression means cancer is still growing while you’re in your treatment. It means the treatment you are going through is no longer controlling the spread of the disease. In such cases, your symptoms may get worse instead of getting better. But this is not where your care stops. It only means your treatment plan needs to be changed. 

Differences to look for

Aspect	Recurrence	Progression
Timing	This is a relapse of cancer after your previous treatment was successful.	This is a continuation of cancer while you are under therapy.
Treatment response	The cancer has already responded to your previous treatment.	The cancer is not responding to your ongoing care.
Disease status	This is cancer’s return after control.	This is cancer’s continuation while you are still under treatment.

How does it impact your treatment?

Cancer recurrence or progression affects your overall treatment. Before making any further decisions, doctors assess your condition. After figuring out whether it's recurrence or progression, doctors may continue with your old treatment, or they may start your new care plan. You should understand your treatment so you can gain clarity and stay aware of your current state.

New plan for better care

You may lose your confidence after hearing of cancer recurrence and progression. But this doesn’t say there is no cure. With the new treatment plan, you will receive the right care you deserve and heal with hope.
