What if a little swelling in your neck region turned out to be life-threatening?
What if a small ulcer in your mouth that never healed was a sign of oral cancer?
Although oral cancer can often be easily identified through visual and physical exams, it is still frequently diagnosed at advanced stages.
Globocan 2022 reports state that oral cancer is the second most common cancer in India and the most common cancer among Indian men. Oral cancer contributes to approximately 39% of total oral cancer cases across the world.
India recorded 143,759 cases of oral cancer and 79,979 deaths due to oral cancer during the year 2022.
In many instances, people have a sore, a small white spot, or a swelling in their mouth that appears harmless. These are often the signs of early-stage oral cancers, which can be treated successfully with personalized treatment and support.
In such cases, one must see an ENT specialist for oral cancer screening and then visit an oral cancer specialist if the physical examination indicates the presence of oral cancer.
In this blog, you will learn about oral cancer symptoms, causes, and treatment in the leading multispecialty hospitals in India. Treatment is possible and curable if detected in time.
What is Oral Cancer?
Oral cancer refers to cancerous growth in the mouth or oral cavity, including:
- Lips
- Gums
- Tongue
- Inner cheeks
- Floor and roof of the mouth
- Tonsils and the back of the throat (oropharynx)
Usually, the sickness starts with a non-healing sore. As time goes by, it might increase and affect the surrounding tissues or lymph nodes. The common form of mouth cancer is squamous cell carcinoma, which originates in the mouth and throat lining, mostly consisting of flat and thin cells.
Common Oral Cancer Causes

Oral cancer does not have a single cause. However, the combination of risk factors increases the chances of getting it.
1. Tobacco Consumption
Tobacco consumption, in both smoked and smokeless forms, can increase one’s oral cancer risk. In India, a large percentage of oral cancer cases are caused by smokeless tobacco, which includes tobacco, gutkha, khaini, or betel quid with areca nut, and are at high risk of oral cancer.
2. Excessive Alcohol Use
Drinking too much alcohol, along with smoking, can increase the chances of getting sick.
3. HPV Infection
Oropharyngeal cancers are associated with human papillomavirus (HPV), especially type 16.
4. Sun Exposure
Prolonged exposure to sunlight may heighten the chances of lip cancer.
5. Chronic Irritation
Poorly fitting false teeth or jagged molars could cause chronic annoyance, increasing the chances of getting cancer.
6. Poor Oral Hygiene
Poor oral hygiene caused by not brushing the teeth properly, inadequate flossing, untreated tooth decay, etc., can increase the risk of oral cancer.
7. Family History of Cancer
Having a positive family history of oral cancer and inheriting genetic conditions that are associated with increased oral cancer risk can make one more susceptible to oral cancer.
Warning Signs and Symptoms of Oral Cancer

Early identification is important, but many symptoms are mistakenly dismissed as minor issues. Here are some things to look out for:
- Non-healing sores inside the mouth or on the lips lasting over two weeks
- Spots in the mouth that may be either red or white
- Discomfort experienced when taking food or talking
- Swelling or masses in the mouth or cheek
- Loss of teeth without a tooth problem
- Long-term unpleasant smell from the mouth
- Change of sound produced or roughness
- Blood is coming out through the mouth
- Lack of feeling in some parts of the mouth or lips
- Continual pain in the throat
Stage 1 oral cancer symptoms are often more subtle. The key to early detection of oral cancer lies in paying attention to persistent oral symptoms and seeing a qualified ENT specialist in India for primary evaluation.
How Oral Cancer is Diagnosed

The first thing to do when you experience oral symptoms is to have a dentist or ENT specialist examine your mouth. Other examinations will be done if any abnormal sores or swellings are seen.
1. Biopsy
They take a small piece of tissue from the suspected area and examine it for cancer cells.
2. Endoscopy
A tiny camera is employed for close examination of the interior of the mouth and throat.
3. Imaging Tests
- CT scan: Performed to determine the extent of the disease’s spread
- MRI: Creates clear pictures of internal structures to evaluate the disease’s presence and spread
- PET Scan: Reveals if the cancer has spread to other organs
4. HPV Testing
Chronic HPV infection is an important risk factor for oral cancer. It can be used to determine the appropriate treatment for oropharyngeal tumours.
Prognosis is most favourable for early-stage oral cancer (Stage 1 or 2), which is detected early.

Stages of Oral Cancer
Stage
|
Tumour Size & Spread
|
Details / Symptoms
|
Stage 1
|
Tumour is ≤2 cm. No lymph node involvement
|
A little wound or blister that might ache a bit and become bigger; most times, it does not hurt
|
Stage 2
|
Tumour size is 2–4 cm, spread to lymph nodes
|
Visible growth or persistent soreness, which may cause pain or difficulty chewing
|
Stage 3
|
Tumour is >4 cm and may have spread to one nearby lymph node (on the same side)
|
Noticeable swelling or lump, pain while swallowing, and possible speech or eating difficulty
|
Stage 4
|
Cancer has spread to deeper tissues, multiple lymph nodes, or distant organs (e.g., lungs)
|
Severe pain, facial swelling or numbness, difficulty speaking or eating, and weight loss and fatigue
|
It is easier to find and cure stage 1 oral cancer, which also has a positive outlook and requires minor medical procedures.
Oral Cancer Treatment Options
Treatment planning for oral cancer depends on its location, stage, and the patient’s overall health.
HCG Hospitals is recognised as one of the best cancer hospitals in Bhavnagar. Equipped with all major cancer treatment facilities under one roof, it offers comprehensive care for different types of cancer.
1. Surgery
Most times, surgery is done before anything else:
- The surgeon will remove the tumour with a small portion of healthy tissue that surrounds it.
- If the cancer surgery leads to deformation of the face, reconstructive surgery may be performed.
- Neck dissection may be performed if the disease has spread to nearby lymph nodes.
2. Radiation Therapy
Powerful radiation beams are used to destroy cancerous cells. It works very well when the cancer is still in its early stage or when used along with an operation.
3. Chemotherapy
Oral or intravenous anti-cancer medications are administered to kill cancer cells throughout the body. Chemotherapy for oral cancer is often combined with other treatments, like radiotherapy, to improve the treatment response.
4. Targeted Therapy
Targeted therapy focuses on identifying specific cellular pathways and molecules that encourage cancer cells to multiply and targeting them to control cancer growth. The side effects are generally less severe compared to those of conventional chemotherapy.
5. Immunotherapy
Immunotherapy involves re-engineering the body's defense against cancer. Commonly employed for progressive or relapsed oral malignancies.
6. Rehabilitation
After treatment, patients may need the following support to seamlessly return to their routine life:
- Speech and swallowing therapy: Specialists help patients regain or adapt their communication and eating abilities through various techniques.
- Nutritional counselling: Trained onco-dieticians help patients with balanced nutritional plans that positively impact their recovery.
- Psychological support: Psychological counselling also plays a pivotal role in the recovery of oral cancer patients.
Recovery and quality of life depend on rehabilitation since treatment may affect how one talks, eats, or looks.
When to See a Doctor
It is important to see an ENT specialist for oral cancer screening if you notice any of the following signs in your mouth:
- A wound that continues for more than two or three weeks and remains painful or uncomfortable
- Problems with swallowing or talking
- Any strange swelling or increase in size inside the mouth
- Hoarseness
- Long-lasting pain in the throat or jaw
- Unexpected loss of weight
Sometimes, just going to a dentist may help find it at an early stage. People should be careful and do everything on time because it can be fatal.
