Oral Cancer - Causes, Symptoms, Stages, Risk Factors, Diagnosis, and Treatment

What Is Oral Cancer?

Oral cancer refers to the presence of cancerous tissue in any part of the oral cavity. Unlike the other types of cancer, oral cancer can involve severalsites in the body. These sites might include the tongue, lips, gums, cheeks, floor, and the surface of the tongue. This type of cancer is very common among smokers. The cause of oral cancer might be very specific, making it very easy to diagnose and treat. However, the diagnosis should be as early as possible for successful treatment outcomes.

What Is the Epidemiology of Oral Cancer?

Men are known to be affected more by oral cancer than women. The common age of occurrence of oral cancer is over 40 years of age. Reports suggest that more than 49,000 new cases are recorded every year in the United States of America. It is a very deadly condition, and each hour, one person is known to die from oral cancer.

What Are the Causes of Oral Cancer?

The main cause of oral cancer is chronic smoking. A severe stage of oral cancer is seen in intense smokers. They also have manifestations of lung cancer in association with oral cancer. The toxic substances present in the cigarettes, such as nicotine, have the tendency to destroy and rupture the healthy cells of the body. Prolonged exposure to nicotine results in the abnormal pigmentation of the oral mucosa that might later convert into a cancerous condition. Passive smokers also suffer a risk of lung and throat cancer. A close relationship with smokers might serve as a potential causative and risk factor for oral cancer. Involving in oral sex with chain smokers can make a healthy individual get exposed to the harmful substance of cigarettes. Also, exchanging saliva with the smoker during kissing or any intimate behavior can serve as a cause.

Chewing tobacco equally carries the risk of oral cancer. Any type of smoking pipes could cause this type of cancer.

What Are the Symptoms of Oral Cancer?

Various symptoms that are associated with oral cancer are:

What Are the Stages of Oral Cancer?

How Is Oral Cancer Diagnosed?

Diagnosis for oral cancer involves the following:

What Are Treatment Options for Oral Cancer?

The treatment options are planned according to the site and size of the tumor.

How Is the Prognosis for Oral Cancer?

The prognosis for oral cancer is predicted by the National Cancer Institute. In a localized type of oral cancer, 83 percent prognosis is expected. If cancer has not spread to any lymph nodes, a 64 percent prognosis is expected. If there is the spreading of cancer to other parts, the prognosis is poor, and it could be less than 38 percent. An overall survival time of five years is noted in patients with oral cancer.

Frequently Asked Questions


1.

How Will the Early Stages of Mouth Cancer Look Like?

The early stages of mouth cancer will rarely cause any pain, but the other symptoms may include:
- Mouth sores.
- Red and white patches.
- Abnormal cell growth like flat patches.
- Unexplained tooth loosening.
- The growing tumor in the gums will weaken the tooth socket.
- Painless lump on the lip, mouth, or throat.
- Unexplained weight loss.
- A canker sore will look like an ulcer, usually with a depression in the center.
- In the middle of the canker sore, it may appear as white, gray, or yellow, where the edges will be red.

2.

How Long Can a Person Live with Oral Cancer?

About one-half of people with oral cancer will live more than five years after being diagnosed and treated. The earlier it is detected, the cure rate is nearly 90% before it has spread to other tissues. But more than half of oral cancers have spread to nearby structures when the cancer is detected.

3.

Is Mouth Cancer Hard or Soft?

In the early stages, oral cancer can be soft, but it will usually get hard as it progresses, sometimes rock hard. As the tumor gets bigger, the tissues surrounding it will also become hard as the tumor invades them.

4.

Can Mouth Cancer Be Aggressive?

Mouth cancer can be very aggressive in the final stage 4, where it has grown into nearby tissue or spread to lymph nodes on the body's opposite side.

5.

Can a Dentist Diagnose Oral Cancer by Just Examining the Oral Cavity?

The dentist cannot diagnose cancer during an examination because, in an oral cancer screening examination, the dentist will look over the mouth inside to check for any mouth sores, red, and white patches or to identify any suspicious-looking areas or growths. Therefore, oral cancer can be diagnosed only with a biopsy where the tissue sample from the affected area is removed and analyzed under a microscope.

6.

What Are the Foods Good For Mouth Cancer?

Good nutrition is necessary during cancer treatment. The foods good for oral cancer include:
- Plenty of fruits and vegetables.
- Whole-grain bread and cereals.
- Lean cuts of meats such as fish, chicken, or turkey.
- Low-fat dairy products.

7.

Can Mouth Cancer Be Cured Without Surgery?

Yes, mouth cancer can be cured without surgery, but with proper medication and a balanced healthy diet.

8.

Can Turmeric Be Helpful In Mouth Cancer?

Turmeric is very helpful in mouth cancer because the curcumin, which is present in turmeric and gives its bright yellow color, possesses anti-cancer properties and effectively controls and eliminates cancerous growth. Dietary turmeric reduces the risk of cancer and prevents metastasis (spread of cancer throughout the body). Turmeric also has the property of reversing the pre-cancerous changes in the mouth.

9.

How Can Oral Cancer Be Diagnosed?

To diagnose oral cancer, the doctor or dentist will initially perform a physical examination of the oral cavity by closely examining the roof and floor of the mouth, the back of your throat, tongue, and cheeks, and the lymph nodes in your neck. If the doctor finds any tumors, growths, or suspicious lesions, they will perform a brush biopsy or a tissue biopsy to be examined under a microscope for cancerous cells. The doctor may also recommend performing one or more of the following tests:
X-rays.
- A CT (computed tomography) scan.
- A PET (positron emission tomography) scan.
- An MRI (magnetic resonance imaging) scan.
- An endoscopy.

10.

Can Oral Cancer Spread Quickly?

Oral cancer takes about months to spread to nearby structures of the mouth and the neck lymph glands. The cure rate is nearly 90% if the cancer is diagnosed before it has spread to nearby structures. But usually, more than half of oral cancers have already spread when the cancer is detected.

11.

Can Oral Cancer Be Healed Effectively?

At the earliest stage of mouth cancer, almost minor surgeries and medications can remove the cancerous cells and ensure that cancer will never return. The chance of survival is higher after treatment if the cancer is detected earlier.
