The word cancer makes us all cringe a little, right? Maybe you've noticed a new lump somewhere on your body and are worried about it? Or maybe a doctor has told you a strange name, 'Mucinous Carcinoma'? Hearing this name probably brings to mind a lot of things. But don't worry. Today, we'll talk about it simply, in a way that you can understand.
What is Mucinous Carcinoma?
Simply put, mucinous carcinoma is a rare type of cancer . What happens in this case is that the cancer cells are made of a substance called mucin . Do you know what this mucin is? It is the main component of the mucus in our body. This mucin is a protein that helps healthy cells function. So, in mucinous carcinoma, this mucin substance that surrounds the cancer cells also becomes part of the cancerous tumor.
Think about it, our body has this mucin, like a protective coating around the cells. Sometimes, when the cells that produce this mucin become cancer cells, the cancer develops along with the mucin that surrounds those cancer cells.
Mucinous carcinoma can develop anywhere in the body. However, it is most commonly seen in the breast . When it develops in the breast, it is also called colloid carcinoma . In addition, this cancer can also develop in other places such as the lungs, colon, or rectum.
What is the difference between Pure and Mixed Mucinous Carcinoma?
Now look, there are two types of this mucinous carcinoma.
1. Pure Mucinous Carcinoma: In this case, the cancerous tumor consists only of cancer cells surrounded by mucin . There are no other types of cancer cells present.
2. Mixed Mucinous Carcinoma: Here, the tumor is formed by a combination of cancer cells surrounded by mucin and other types of cancer cells .
Of the two, the 'Pure' type is generally considered a bit milder than the 'Mixed' type. We'll talk about that later.
What is the difference between Mucinous Carcinoma and Adenocarcinoma?
These two names are somewhat similar, so they can be confused. However, there is a slight difference between the two.
Adenocarcinoma is a type of cancer that starts in our mucous glands. Simply put, the glands that produce mucus. These glands are located in the mucous membrane that lines areas like our digestive tract. People with adenocarcinoma often produce too much mucin.
However, Mucinous Carcinoma starts with a protein called mucin . That is, mucin is found around every cell. In this type of cancer, the mucin itself becomes part of the tumor. Do you understand the difference?
How common is this condition?
What is mucinous carcinoma?It's a really rare type of cancer. Not every cancer patient develops it.
- Of all breast cancers , approximately 7% are of this type.
- About 3% of ovarian cancers.
- Less than 5% of lung cancers.
- About 9% of rectal cancers.
- Less than 10% of endometrial cancers.
- About 15% of colon cancers.
Looking at these statistics, you can see that this is not as common as other types of cancer.
What causes this?
In fact, any cancer is caused by cells in our body not dividing, growing, or dying normally. It's hard to say exactly what causes mucinous carcinoma, specifically. Doctors are still researching it. However, there are some factors that increase the risk of cancer in general:
- Age: Some cancers, for example breast cancer, are more likely to develop with age.
- Environment: Exposure to secondhand smoke or certain chemicals may increase the risk.
- Family history: If someone in your family has had cancer, you may be slightly more likely to develop cancer.
- Genetics: Changes (mutations) in certain genes can increase the risk of cancer.
- Lifestyle: Things like drinking alcohol, a low-fiber diet, and leading a sedentary lifestyle without exercise can be risk factors for some cancers.
The important thing is that not everyone who has these factors will develop cancer. Also, someone who does not have any of these factors can also develop cancer. So don't worry too much about this.
What are the symptoms?
The symptoms of mucinous carcinoma are similar to those of other types of cancer. Symptoms may vary depending on where it occurs.
Symptoms of mucinous carcinoma of the breast:
The first sign may be a lump in the breast tissue . In addition:
- Armpit or breast pain.
- Changes in the breasts (change in size or shape).
- Nipple discharge.
- The skin is swollen, sunken, or pitted.
Symptoms of mucinous carcinoma of the colon or rectum:
These are similar to other symptoms of colorectal cancer:
- Abdominal pain or cramping.
- Blood in the stool or rectal bleeding.
- Change in bowel habits (such as constipation or diarrhea).
- Weight loss for no reason.
- Weakness.
Symptoms of mucinous carcinoma of the lungs:
- Chest pain.
- Persistent cough.
- Coughing up blood.
- Headache (Hisē reduma - Sinhala for headache, not Georgian). Sorry, there was a mistake here. Headache.
- Hoarseness of voice.
- Difficulty breathing (Dyspnea).
If you have one or more of these symptoms, it doesn't necessarily mean you have cancer. However, if you have any of these symptoms, it's best to see a doctor and get checked out.
How do you diagnose this?
If a doctor suspects you have mucinous carcinoma, they may do several tests:
- Imaging tests: These include ultrasound scans, MRI scans, or CT scans. These can look at the nature and size of the tumor inside the body.
- Mammogram: A special X-ray test used to examine breast tissue.
- Biopsy: This is the most definitive way to confirm cancer . This involves taking a small sample of the suspicious tissue and examining it under a microscope. This is the only way to tell for sure whether it is cancer, and if so, what type of cancer it is.
What is the treatment?
Treatment for mucinous carcinoma depends on the type of cancer (pure or mixed), the stage of the cancer, and your overall health.
Let's also learn a little about cancer staging:
- Stage I, II, or III means that the cancer is in one part of your body. The higher the stage, the more the cancer has spread to surrounding tissues.
- Stage IV means the cancer has spread (metastasized) to distant parts of the body.
The good news is that mucinous carcinoma is often less aggressive than other types of cancer . This means that it spreads more slowly. Oncologists can use the following treatments for it:
- Hormone therapy: A treatment that lowers the levels of estrogen (a female hormone) in your body. This is often effective for mucinous carcinoma of the breast.
- Surgery: Remove cancer cells.
- Chemotherapy: Giving drugs that kill cancer cells.
- Radiation therapy: To kill cancer cells or slow their growth.
- Targeted therapy: Giving drugs that identify and attack specific parts of cancer cells.
- Immunotherapy: Giving drugs that help your own immune system recognize and destroy cancer cells.
The medical team will discuss with you and decide which treatment is right for you.
How to reduce the risk?
There is no way to 100% prevent the development of mucinous carcinoma.However, in general, it is very important to follow a healthy lifestyle to reduce the risk of developing any cancer:
- Maintain a healthy weight that is appropriate for your gender, age, and body type.
- Eat a nutritious diet that includes fruits, vegetables, healthy fats, lean protein, and whole grains.
- Exercise regularly, including both strength training and aerobic exercise.
- Limit your intake of alcohol and processed meats .
- Follow safe behaviors such as safe sex and avoiding drug use.
- Quit smoking .
What is the prognosis/cureability? (Prognosis)
Most mucinous carcinomas respond well to treatment . As mentioned earlier, they are usually less aggressive than other types of cancer. This means they are less likely to spread to lymph nodes or other tissues.
As with any cancer, the sooner treatment is started, the better the chance of a cure . Pure mucinous carcinoma generally has a better prognosis than mixed mucinous carcinoma. In one study, the five-year survival rate for pure mucinous carcinoma was close to 100%.
After any cancer treatment, you will need to see your doctor for regular check-ups (follow-ups) . These appointments will monitor your overall health and help detect and treat the cancer early if it recurs.
What questions should you ask the doctor?
If you are diagnosed with mucinous carcinoma, you may want to ask your doctor these questions:
- Do I have Pure or Mixed Mucinous Carcinoma?
- What other tests do I need to do to diagnose mucinous carcinoma?
- What treatment options do I have?
- What are the chances of mucinous carcinoma recurring after treatment?
In addition to these questions, don't be afraid to ask your doctor anything you have on your mind or any doubts you may have.
Is mucinous breast cancer serious?
Mucinous carcinoma of the breast, especially pure mucinous carcinoma, is usually less aggressive than other types of breast cancer . That is, it spreads slowly.
Can this mucinous carcinoma spread?
Yes, mucinous carcinoma can spread. It can spread to surrounding tissue or other parts of the body. However, it is less likely to spread than other types of cancer cells .
Finally, things to remember (Take-Home Message)
Mucinous carcinoma is a rare type of cancer. Although it can develop anywhere, it is most commonly found in the breast. It can also develop in other places, such as the lungs, colon, and rectum. The symptoms are similar to other types of cancer.
But most importantly, it is usually a less aggressive cancer, and has a lower chance of spreading (metastasizing) to lymph nodes . If doctors detect it early, it often responds well to treatment .
Therefore, if you have any doubts or fears about this, do not suffer alone and seek medical advice. Early detection and proper treatment can lead to good results.
👩🏽⚕️ Additional questions (FAQs)
💬 What type of cancer is Mucinous Carcinoma?
Normally, our bodies produce mucus (mucin) to keep our bodies moist. But in this rare type of cancer, a large layer of this 'mucin' forms around cancer cells and the cancer grows inside it. This most often occurs in the breasts, colon, and ovaries.
💬 Is this cancer dangerous? Does it spread quickly?
Surprisingly, the thick layer of mucus that surrounds these cancer cells makes it difficult for the cancer cells to spread to other organs (blood or lymph nodes). Therefore, compared to other cancers (e.g., common breast cancer), this cancer is a slow-growing cancer with a very high cure rate.
💬 What is the main treatment for this?
If caught before it spreads to other areas, the main and most successful treatment is surgery to completely remove the tumor (lumpectomy or mastectomy). Radiation and hormone therapy are also given if necessary.
