If your mammogram shows "abnormal cells," it's normal to feel scared and anxious. "Is this cancer? What will happen to my life?" You may be wondering. But don't panic. It may not be as serious as you think. In most cases, this is the very early stage of breast cancer, known as "Stage 0." That's what we're talking about today. Let's take a quick look at what it really is, whether it's something to be concerned about, and what treatments are available.
What is this 'Stage 0'?
Simply put, stage 0 means that the cancer cells or abnormal cells are still where they first started, in the milk ducts or lobules of the breast. These cells have not yet spread (invaded) into the surrounding healthy tissue. Doctors call this condition "in situ." That means "where it was."
Think of the milk ducts in the breast as a system of pipes in a house. These abnormal cells are only inside those pipes. They haven't yet broken through the walls of the pipes and spread to other parts of the house. That's what's happening here. This is very important, because if it's detected at this stage, it can be treated and almost completely cured .
There are two main types of 'stage 0'. Let's look at them separately.
| Specialty | DCIS (Ductal Carcinoma In Situ) | LCIS (Lobular Carcinoma In Situ) |
|---|---|---|
| Meaning | Abnormal cells in the milk ducts of the breast. | Abnormal cells in the milk-producing glands (lobules) of the breast. |
| Severity | This is considered a 'pre-cancer' condition. If left untreated, it can develop into invasive cancer in the future. | This is not cancer. However, it is considered a 'risk marker ' that increases the risk of developing cancer in both breasts in the future. |
| Identification | It can often be detected with a mammogram. | Often, a lump cannot be felt. It is found incidentally during a breast biopsy performed for another reason. |
| What to do | Treatment should be started immediately. | Close observation and frequent discussions with the doctor are necessary. Treatment may be necessary to reduce the risk. |
What are the treatments for DCIS?
Because DCIS can become a cancer that spreads in the future, it is essential to treat it as soon as it is detected. Fortunately, treatments are very effective.
1. Surgery
This is the main treatment. There are two types of surgery.
- Lumpectomy: This involves removing only the lump or area with abnormal cells, along with some healthy tissue around it. It does not remove the entire breast.
- Mastectomy: In some cases, if the DCIS is large or has spread throughout the breast, doctors may recommend removing the entire breast. This decision is made after a thorough discussion with your doctor.
Some women also decide to have breast reconstruction surgery after a mastectomy. It is a completely personal decision.
2. Radiation Therapy
Radiation therapy is usually given after a lumpectomy. This uses high-energy rays to destroy any microscopic abnormal cells that may remain after surgery. It's like cleaning the area thoroughly after surgery, reducing the risk of the problem recurring.
3. Hormone Therapy
If your DCIS is hormone-receptor positive, your doctor may recommend hormone therapy after surgery. These medications reduce the risk of new cancer developing in both breasts in the future.
What do you do for someone with LCIS?
As we said earlier, LCIS is not cancer, but a warning sign for the future . Therefore, the way to treat it is a little different. The main thing here is not to panic, but to act in a planned manner.
- Close monitoring: This is the most important thing. It is essential to have regular breast exams, mammograms, and other necessary scans as recommended by your doctor.
- Hormone therapy: Women with LCIS may also be given hormone therapy (e.g., Tamoxifen) to reduce the risk of developing cancer in the future.
- Preventive Surgery: This is not something everyone can do. However, women who are at very high risk of developing breast cancer sometimes make this decision. Who falls into this high-risk group?
- If a close family member (mother, sister) has had breast cancer.
- If you have been diagnosed with gene mutations that increase your risk of breast cancer, such as BRCA1 or BRCA2 .
In such cases, some women decide to undergo a double mastectomy to avoid future risks. This is a very personal and serious decision, and should be made after a very thorough discussion with a doctor.
How do you choose what suits you best?
After reading all of this, you may be wondering, "What's best for me?" The answer lies with you, with your doctor.
Remember, 'Stage 0' is not a death sentence. This is a highly treatable, early-detected condition.
Your doctor will recommend the best treatment plan for you, taking into account the nature of your condition (DCIS or LCIS), its size, your age, family history, and your personal preferences. Be sure to discuss any questions or concerns you have with your doctor . Talking openly with him is the best decision you can make.
Take-Home Message
- 'Stage 0' breast cancer means that the abnormal cells are stuck where they started (in the ducts or glands). They have not yet spread to surrounding tissue.
- DCIS is a condition that requires immediate treatment because it can become a spreading cancer if left untreated.
- LCIS is not cancer, but rather a warning sign of future cancer risk, and requires close medical monitoring.
- Methods such as surgery, radiation therapy, and hormone therapy are very successful and have a high cure rate.
- It is important to discuss all your options, their pros and cons, with your doctor and make the decision that is best for you. It is important to be informed and not afraid.
