It's hard to put into words the relief you feel when your doctor says, "You're completely cured now," right? That's the phrase we all love to hear. But did you know that in medicine, the word "cure" has a much deeper meaning than we think? Sometimes we can misunderstand this word. So today, let's talk about what this "cure" really means, how it differs from "treatment," and what these words really mean, especially when talking about diseases like cancer.
What is the difference between "Cure" and "Treatment"?
Although many people think that these two words are the same, there is a clear difference between the two. Simply put, treatment refers to the things we do to cure, control, or reduce the symptoms of a disease. That means taking medication, having surgery, and various therapies. A cure is the result of those treatments. That means that after treatment, the disease disappears completely and never comes back.
Think of treatment as a journey. We may encounter many different stops along the way. "Complete healing" is just one stop on that journey. There are other outcomes beyond that.
This becomes more clear from the table below.
| Treatment outcome | Simply put... |
|---|---|
| Complete cure | Your illness will completely go away. It will not come back. For example, when you take antibiotics for a bacterial infection, the bacteria will be completely destroyed and the illness will be cured. |
| Disease Prevention | Preventing a disease before it develops. For example, getting the HPV vaccine can protect you from HPV, which can cause cancers like cervical cancer. |
| Disease Management | Even though the disease cannot be completely cured, it can be controlled and lived well. For example, a person with diabetes can take insulin and control their blood sugar levels to live a healthy life. |
| Palliative Care | To improve the quality of life of someone living with an incurable disease by reducing symptoms and pain. While this does not cure the disease, it helps the patient live with comfort and dignity. |
Are "Cure" and "Recovery" the same thing?
We often confuse these two words. "Recovery" means getting better day by day. It can be a long journey. But it doesn't mean that the illness is completely gone.
The best example is drug addiction. A person recovering from drug addiction is in a "recovery" process. That means that day by day, they are getting away from drugs and getting used to a better life. But that doesn't mean they will never have the urge to use drugs again. It's a daily decision.
But "complete cure" means the problem is completely gone. There's no need to think about it again.
What is 'cure' and 'remission' in cancer?
The meaning of these words becomes more complicated when talking about cancer. Oncologists who treat cancer are often hesitant to use the term "complete cure." Instead, they use the term "remission."
Simply put, "complete cure" means that the cancer will never come back. But "remission" means that no such guarantee can be given.
There are two types of remission:
- Complete Remission: In this case, your doctor can't find any cancer cells in your body through tests or scans. You don't have any symptoms. However, there may still be very small amounts of cancer cells hidden somewhere in your body that aren't detected by the tests. Or, you may be 100% cancer-free.
- Partial Remission: In this case, there are still cancer cells in your body, but they are much fewer than when treatment started. If there were any tumors, they may have shrunk.
When the doctor says, "Your cancer is now in remission," it's great news. But it can also be a little disconcerting, because we want the assurance that "it will never come back." Cancer can be in remission for weeks, months, or even years. It may not come back for the rest of your life. But sometimes, it can come back (recurrence). If that happens, you'll have to start new treatments.
So, can cancer really be 'cured'?
The short answer is, "Not yet." But the long answer is more complicated.
When we hear the word "cancer," we think of it as one disease. But there are actually more than 100 types of cancer. Each of these types of cancer differs in how it affects the body, its severity, the treatments needed, and how it responds to treatment.
But the good news is that some cancers, especially if detected early, can be completely cured with treatment. This is what many of us hope for when we say "complete cure." It is thanks to these advances in medicine that people are now surviving cancers that were fatal just a few decades ago. That is why some doctors call some cancers "curable" when detected early.
What cancers have the highest cure rate?
A doctor is more likely to say your cancer is "cured" if you've been in remission for 5 years or more. That's because most cancers come back, and it's more likely to happen within the first 5 years.
One important metric that doctors use when talking about cancer outcomes is the "five-year relative survival rate." Simply put, this is how many people out of 100 diagnosed with a particular type of cancer are still alive after 5 years. While this can't tell you 100% for sure what will happen to you, it can give you a general idea of how the disease will progress.
Most cancers that are detected and treated early have a "five-year survival rate" of over 90%. That means that 90 out of 100 people are still alive after 5 years.
Below are some types of cancer that have such a high cure rate.
| Cancer type | Survival rate (at the initial stage) | Why is the chance of recovery higher? |
|---|---|---|
| Breast Cancer | ~99% | Regular screenings can help detect breast cancer early, and targeted treatments have been developed for various types of breast cancer. |
| Cervical Cancer | ~92% | This is a very slow-growing cancer. Regular Pap smears can detect abnormal cells before they become cancerous. |
| Prostate Cancer | ~99% | This is also a very slow-growing cancer. It can be detected and treated before it spreads (metastasizes) to other parts of the body. |
| Testicular Cancer | ~99% | Surgical removal of the cancerous testicle is often a complete cure, and this cancer responds very well to chemotherapy. |
| Thyroid Cancer | ~99% | Often a slow-growing type, surgically removing the thyroid gland often completely removes the cancer. |
| Melanoma - a type of skin cancer | ~99% | Skin changes (spots, warts) can be easily detected early because they are easily visible. Melanoma on the surface of the skin can be completely removed with surgery. |
Talk to your doctor about this.
If you have a medical condition, it's normal to feel scared and curious when you hear words like "complete cure," "survival rate," and "disease remission." The most important thing is to talk openly about all of this with your doctor.
Don't be afraid of being told "incurable." It doesn't mean you can't live a good life. Instead, ask your doctor about what treatments can help you live a good life, whether you can stay symptom-free, and whether you can return to your normal life.
It is very important that you and your doctor have a common understanding of the true purpose of your treatment. This will bring you great peace of mind.
Take-Home Message
- "Complete cure" means the disease is completely gone and will never come back.
- "Treatment" refers to things done to cure, control, or reduce symptoms of a disease. "Complete cure" is only one outcome of treatment.
- In cancer, doctors prefer to use the term "remission" rather than "cure" because it is difficult to give a 100% guarantee that cancer will not come back.
- Some types of cancer, such as breast, cervical, and prostate cancer, can be treated very successfully and almost completely cured if detected early.
- Your doctor is the best person to talk to about your condition and treatment plan in detail. Don't be afraid to ask questions and share your thoughts.
