Mouth cancer symptoms and causes – Latest 2022

Mouth cancer, also known as oral cancer or cancer of the oral cavity, refers to a variety of cancers that begin in the mouth. These are most often seen on the mouth’s lips, tongue, and floor, but they can also develop in the cheeks, gums, roof of the mouth, tonsils, and salivary glands. Head and neck cancers are the most common type of mouth cancer. It affects men more frequently than women and is more likely to strike individuals who are over 40. Smoking in combination with excessive consumption of alcohol is a crucial risk factor.

Mouth cancer, if not detected early, may necessitate surgery, radiation therapy, and chemotherapy. It is also potentially deadly, with a five-year survival rate of around 50%. Because a failure to recognize early symptoms contributes to this poor prognosis, detecting oral cancer early is important for effective treatment.

Mouth cancer can cause a number of health problems, interfering with everyday routines such as speaking, chewing, and swallowing. This results in almost unpreventable bruises on the mouth, lips, and tongues – the organs vital for those activities.


Mouth Cancer Types:-

The type of cancer indicates the type of cell in which the disease began. Squamous Cell Carcinoma (SCC) is the term used to describe the majority of mouth and oropharyngeal cancers that begin in squamous cells. The following are some other cancers of the mouth and oropharynx.

  • Cancer of the salivary glands
  • Cystic adenoid tumors
  • Carcinoma of the basal cell
  • Lymphoma
  • Melanoma


Some unusual parts and growths in the mouth and oropharynx may not be cancerous. These, however, may contain abnormal cells that, if left untreated, can cause cancer. These areas are thought to be precancerous.

What are the Signs and Symptoms of Mouth Cancer?

Understanding the symptoms of mouth cancer is important because it helps people determine how urgently they require a doctor’s consultation. As a result, read on to learn more about it –

  • One of the early symptoms of mouth cancer is ulcers or bruises in the mouth, lip, and tongue that do not cure for weeks.
  • The inner lining of one’s mouth and tongue may also develop red or white spots.
  • Teeth become loose as a result of gum cancer, or the socket does not heal easily after the tooth is removed.
  • Mouth cancer symptoms can also include growths inside the mouth.
  • A patient may also experience ear pain and dysphagia, or difficulty swallowing food.
  • Bleeding from the mouth linings and infections within the oral cavity are also early-stage symptoms of mouth cancer.


These mouth cancer symptoms will make it easier for people to assess their own health. They should, however, seek medical attention right away to determine whether they have this cancer.

What Causes Mouth Cancer?

Individuals must be aware of all of the causes of mouth cancer. This way, they can be aware of the agents causing this disease and, as a result, reduce their exposure. So read on to find out.

  • Squamous cell carcinoma is the primary cause of this disease in most cases (nearly 90%).
  • Addiction to smoking, tobacco, and alcohol can all lead to mouth cancer.
  • HPV, or Human Papillomavirus, is transmitted sexually and makes people susceptible to this cancer.

Other factors that increase the risk of this disease include excessive UV exposure and a weakened immune system.

Different stages of Mouth Cancer

The stages of Mouth Cancer are as follows.

  • Mouth Cancer Stage 0:- Stage 0, also referred to as carcinoma in situ, is the most dangerous. It refers to cancer cell that has developed in the lips or the lining of the oral cavity.
  • Mouth Cancer Stage I:- Stage I cancer refers to the very early stages of the disease. The tumor is no bigger than 2 cm through, and the disease hasn’t spread to the lymph nodes.
  • Mouth Cancer Stage II:-A tumor in stage II is larger than two centimeters but less than four cm. Cancer has not spread to the lymph nodes in stage II.
  • Mouth Cancer Stage III:- Cancer in the third stage can grow to be larger than 4 cm in diameter or expand to the lymphatics in the neck.
  • Mouth Cancer Stage IV:- This is the most advanced stage of Mouth Cancer. At this point, cancer may have spread to other parts of the body.

Tumors in stages III and IV appear to be more likely to recur than those in earlier stages.


Mouth cancers are one of the most preventable types of cancer. The most important thing you can do to avoid mouth cancer is to never start smoking or to stop smoking if you already do. Regular dental visits will help ensure that any symptoms of mouth cancer are detected as early as possible.
