Do you have cancer in your jaw? (Jaw Cancer) Don't be afraid, let's talk about this!

Have you ever wondered if you could get jaw cancer? You may have noticed a small swelling or a sore that won't heal in your mouth or jaw and felt a little scared. Jaw cancer is actually a rare condition, but it's important to be aware of it. Because, if it's detected early, there's a good chance that this condition can be treated successfully. So, let's talk about jaw cancer in more detail today, shall we?

What is Jaw Cancer?

Simply put, jaw cancer is a very rare type of cancer that occurs in the mouth. If doctors find cancer in your jaw, it often starts somewhere else in your mouth. For example, it may start somewhere else in your tongue, salivary glands, or palate, and then spread to your jaw.

However, very rarely, malignant tumors can start inside your jawbone. Or they can start in the tissues that make teeth (`(odontogenic tissue)`). These malignant tumors are not like the normal benign tumors that you see. They can spread outside of your mouth to other parts of your body.

That's why it's important to see a doctor as soon as possible if you think you have symptoms of jaw cancer. Some types of cancer can be completely cured if detected early and surgically removed.

Are there types of jaw cancer?

Yes, there are different types of oral cancer. They are called carcinomas, sarcomas, and carcinosarcomas. These names refer to the type of tissue in which the cancer cells begin. Most oral cancers, including those affecting the jaw, are of the type called squamous cell carcinomas (SCC). These SCCs begin in the tissues that cover the surface of the body, including the mouth. They account for 90% of oral cancers.

Here are some of the most common types of jaw cancer:

• Ameloblastic Carcinoma: This develops from the tissue that forms the enamel of your teeth. It most often develops in the lower jaw, near the back teeth. It can occur alone, or rarely, it can develop into a benign ameloblastoma that becomes cancerous.
• Clear Cell Odontogenic Carcinoma: This usually occurs in the lower jaw. It gets its name from the way its cells look under a microscope.
• Ghost Cell Odontogenic Carcinoma: This is a very rare type of cancer. Only 50 cases have been reported in medical research. It can occur alone, or it can develop from a cyst in the jaw that calcifies and becomes cancerous.
• Osteosarcoma: This arises from the bones themselves. Osteosarcoma usually arises in long bones such as the hip bone. It rarely begins in the jaw bone.
• Primary Intraosseous Carcinoma: This usually develops in the back of the lower jaw. It can occur alone or as a result of a noncancerous growth that becomes cancerous. Although it develops in the jawbone, it is made up of the same types of cells as carcinoma.
• Sclerosing Odontogenic Carcinoma: This is also extremely rare. Only 15 cases have been reported in medical research.

Now you might think these names are a bit complicated. That's true, these are special names used by doctors. The most important thing for you is to see a doctor if you notice anything unusual.

How common is Jaw Cancer?

In fact, jaw cancer is very rare . Only 4.5% of all squamous cell carcinomas (SCC) worldwide occur in the head and neck. Even then, it rarely starts in the jaw. For the most part, a lump you see on your jaw or near your teeth is more likely to be benign.

However, it's best to have any new lump checked by your doctor. That way, you can get a proper diagnosis.

What are the symptoms of Jaw Cancer?

In the early stages, there are not many symptoms. But as the tumor grows, you may notice changes. Most tumors develop in the lower jaw (Mandible), but they can also develop in the upper jaw (Maxilla).

Symptoms of jaw cancer may include:

• A lump or swelling in the jaw (may or may not be painful).
• Mouth sores, they hurt, they don't heal, they bleed easily.
• Red or white patches in the mouth that won't go away.
• Difficulty swallowing (Dysphagia).
• Difficulty opening your mouth.
• Changes in your facial appearance.
• Feeling like your teeth are moving around, or your teeth are loose.
• A change in the way the teeth fit together (bite).
• Fever.

Imagine, while you're brushing your teeth, you suddenly get a small lump on your jaw. At first, you might ignore it. But if it's still there after a few days, or if it seems to be getting bigger, you should definitely see a doctor.

Why does jaw cancer occur?

The way our body's cells grow and divide is controlled by instructions in `DNA`. When changes in this `DNA` occur (`Genetic Mutations`), problems can occur in the way cells function. Problems with the code in this `DNA` can cause cells to function irregularly and form tumors. Scientists are still researching the `DNA` changes that cause the different types of tumors associated with these jaw cancers.

Sometimes, a non-cancerous (benign) cyst on the jaw can turn into a cancerous (malignant) cyst, causing jaw cancer. But most of the time, non-cancerous cysts on the jaw remain the same and do not become cancerous.

Your doctor can monitor you for noncancerous growths that could be a risk factor for jaw cancer.

Who is at higher risk of developing jaw cancer?

These factors may increase your risk of developing jaw cancer:

• Age: Jaw cancer most often develops in people over the age of 55.
• Gender: Men are at higher risk.
• Tobacco use: Tobacco use is the biggest risk factor for oral cancer . Tobacco contains more than 60 cancer-causing chemicals (carcinogens). Breathing in secondhand smoke also increases the risk.
• Alcohol use: Excessive alcohol consumption is a major risk factor for head and neck cancers. The combination of tobacco use and excessive alcohol consumption increases the risk of developing oral cancer by about 30 times. Therefore, if you are a smoker, it is essential to quit and limit your alcohol consumption.
• HPV infection: Cancer-causing strains of the human papillomavirus (HPV), especially HPV-16, increase your risk. HPV-related oral cancers are now on the rise.
• Chewing betel nut: Betel nuts contain carcinogens. Chewing betel nut is a cultural tradition in some parts of Asia. However, it increases the risk of oral cancer.
• Having a family history of oral cancer: If someone in your immediate family (e.g., a parent, child, sibling) has had oral cancer, you may also be at increased risk.

How does a doctor diagnose jaw cancer?

Your doctor will first examine you physically to check for any new lumps or swellings. They will review your medical history and ask about your symptoms. They may also do blood tests to check for substances in your blood that are linked to cancer (`tumor markers').

Imaging tests are used to look at tumors inside the body. These include:

• X-rays
• `Magnetic Resonance Imaging (MRI)`
• `Computed Tomography Scan (CT Scan)`

In addition, you may need to have a biopsy. This involves taking a small piece of tissue from the lump and sending it to a lab to see if there are any cancer cells. A biopsy can also tell how fast the jaw cancer is spreading.

What are the treatments for Jaw Cancer?

Most people with jaw cancer will need surgery to remove the tumor. Sometimes, surgery may also be needed to remove the jaw or tissue around the jaw. Types of surgery used to treat jaw cancer include:

• Mandibulectomy: Removal of part of the lower jawbone. If a small portion is removed, it is called a partial mandibulectomy. If a larger portion is removed, it is called a segmental mandibulectomy.
• Maxillectomy: Removal of all or part of the upper jawbone.

Your doctor will try to remove as much tissue as possible to completely remove the cancer, while leaving some healthy tissue. But in some cases, surgery can change your appearance. But there are treatments that can help with that too. Your doctor may recommend reconstructive surgery to rebuild your jaw, or dental implants to replace teeth removed during surgery.

Depending on the type of jaw cancer, you may also need additional cancer treatments. These may include:

• Radiation Therapy: This involves using a machine to deliver high-energy beams of radiation to shrink tumors. Radiation therapy may be given as the main treatment if you are not healthy enough to have surgery. Or, radiation therapy may be given to kill any remaining cancer cells after surgery.
• Chemotherapy: This involves using drugs to kill cancer cells. Chemotherapy is not a common treatment for jaw cancer, but it can be given in conjunction with radiation therapy after surgery.
• Palliative Care: This helps control symptoms and side effects of cancer treatment. Palliative care can help people with a good outlook, as well as those receiving hospice care. If you think you might benefit from palliative care, ask your doctor.

What happens if you have jaw cancer?

Currently, the five-year survival rate for all oral cancers, including jaw cancer, is about 68%. But your prognosis depends on the type of jaw cancer. Some types of cancerous tumors that start in the jawbone, such as osteosarcoma and primary intraosseous carcinoma, are fast-growing. But other types grow more slowly. If the disease is detected early and treated, it can be cured before it spreads.

Many cancerous jaw tumors can `recur` after treatment. Your doctor will work with you to schedule follow-up appointments to help keep you in `remission`. Treating a tumor at the first sign of recurrence can help keep jaw cancer under control.

When should I see a doctor?

If you have new lumps, sores, or rough patches in your mouth that don't get better within two weeks, see a doctor right away . New lumps can often be a sign of a benign condition, but you should see a doctor to be sure.

Regular dental visits increase the chance of finding a tumor early, before symptoms appear. Often, tumors can be detected on routine dental X-rays. If they are caught before they spread or cause problems, you have a better chance of getting treatment that can stop the cancer from spreading or stopping it from spreading.

What questions should you ask the doctor?

You can ask the doctor questions like these:

• What type of jaw cancer do I have?
• What tests do I need to do to see if it has spread?
• What kind of treatment do I need?
• What is the chance of the tumor coming back after surgery?
• How should I take care of myself while recovering from surgery?

If you notice a new lump on your jaw, or if you have other symptoms of jaw cancer, see a doctor right away. Most people with oral tumors – both malignant and benign – will need surgery to remove them. With jaw cancer, you may need additional treatments, such as radiation therapy, to stop the tumor from coming back. Your doctor will explain which treatment is best for you, depending on the type of tumor you have.

The most important things for you to remember (Take-Home Message)

So, I hope you have gained some understanding from what we have discussed about Jaw Cancer. The most important thing to remember is:

• Awareness: It's important to be aware of any disease. Although jaw cancer is rare, being aware of it can help you recognize the risk symptoms early.
• Avoid risk factors: Avoid tobacco use and excessive alcohol consumption , which are the main causes of oral cancer.
• Don't ignore symptoms: If you notice anything unusual in your mouth or jaw – a lump, a sore that won't heal, a spot – and it's been there for more than two weeks, definitely see a doctor.
• Get regular dental checkups: A dentist can identify any problems at an early stage.
• Don't be afraid, seek advice: If you have any doubts, talk to a doctor and get advice. Early detection is the key to successful treatment.

Wishing you all good health!
