Oral Cancer Treatment in Delhi NCR
Comprehensive diagnosis, personalized care, and advanced therapies by Dr. Manish Singhal.
Understanding Oral Cancer
657,000 new cases of oral cancer are diagnosed each year, for such huge numbers, the risk factors are many, add to that the vulnerability brought in by Covid-19, and something needed to change during the pandemic to make cancer treatment and management safe for the patients. So, Dr. Manish Singhal , a renowned Oncologist in India and the best Oral Cancer doctor in Noida, and his team are offering video consultations, home chemotherapy services, change of treatment plans, and more to combat the situation.
High-risk factors for oral cancer include smoking, chewing tobacco or using snuff, drinking excessive alcohol, having unprotected sun exposure to the lips, and chewing betel nut. The risk is even higher when people have more than one or more of these unhealthy habits.
What Causes Oral Cancer?
Knowing the root causes helps in better prevention and early intervention.
Tobacco Use
Smoking cigarettes, using chewing tobacco and gutkha are the leading causes of oral cancer, as they damage mouth tissues over time.
Excessive Alcohol
Heavy drinking irritates the mouth lining and, when combined with tobacco use, multiplies the cancer risk.
HPV Infection
Certain strains of HPV, especially HPV-16, can infect the mouth and throat, leading to cancerous changes in cells.
Common Signs & Symptoms
Know the common indicators that should never be ignored.
Oral cancer often starts silently, showing early signs such as mouth sores, red or white patches, or difficulty chewing. Over time, pain, bleeding, or swelling in the mouth and jaw may develop. Detecting these symptoms early and visiting a dentist or ENT specialist for evaluation can make treatment highly effective and life-saving.
Non-Healing Mouth Sores
Persistent ulcers in the mouth that do not heal within two weeks.
Red or White Patches
Discolored spots, gums, or tongue that may become painful or rough.
Difficulty Chewing or Swallowing
Pain, stiffness, or discomfort while eating, drinking, or speaking.
Lump or Swelling in the Mouth
Any unexplained mass or swelling that persists for long periods.
Non-Healing Mouth Sores
Persistent ulcers in the mouth that do not heal within two weeks.
Red or White Patches
Discolored spots, gums, or tongue that may become painful or rough.
Difficulty Chewing or Swallowing
Pain, stiffness, or discomfort while eating, drinking, or speaking.
Lump or Swelling in the Mouth
Any unexplained mass or swelling that persists for long periods.
Staging for Oral Cancer
Understanding how oral cancer is classified helps determine the right treatment and predict outcomes.
In the first stage, the tumor is small (less than 2 cm) and confined to one specific area of the mouth, such as the tongue, gums, inner cheek, or floor of the mouth.
The cancer has not yet spread to nearby lymph nodes or deeper tissues, making it the most treatable and curable stage.
Symptoms may be subtle — a small ulcer, sore, white or red patch, or mild discomfort that doesn’t heal for weeks.
With early detection through oral screening or biopsy, treatment (usually surgery or radiation) can completely remove the tumor and prevent progression.
At this stage, the tumor increases in size (2–4 cm) but remains localized within the mouth.
The cancer cells may begin to invade deeper layers of the oral tissue but still haven’t reached the lymph nodes or distant areas.
Symptoms become more noticeable — such as pain, difficulty chewing, bleeding, or visible swelling in the affected area.
Early treatment (a combination of surgery and radiation therapy) can still offer an excellent prognosis, with a high chance of full recovery.
In Stage 3, the cancer extends beyond its original site, spreading to nearby lymph nodes, jaw muscles, or surrounding tissues.
The tumor may be larger than 4 cm, and one lymph node (on the same side of the neck) might be involved.
Patients may experience difficulty swallowing, jaw stiffness, persistent pain, or numbness in the face or mouth.
At this stage, treatment typically includes a combination of surgery, radiation, and chemotherapy to remove the tumor, control local spread, and prevent further progression.
Stage 4 represents the most advanced phase of oral cancer, where the disease spreads extensively
within the mouth, to multiple lymph nodes, or even to distant organs such as the lungs, throat, or bones.
Tumors are often large, invasive, and may cause visible facial deformities or severe pain.
Symptoms can include difficulty speaking, swallowing, or opening the mouth, unexplained weight loss, and persistent bleeding or ulcers.
Treatment becomes more complex and may involve advanced surgery (sometimes reconstructive), radiation therapy, chemotherapy, targeted therapy, or immunotherapy.
The focus may be on both controlling the disease and maintaining quality of life, depending on the spread and patient’s condition.

Advanced Treatments for Oral Cancer
Cutting-edge treatments offering renewed hope and longer, healthier lives.
The treatment procedure depends on several factors, which include the type, stage, grade and also the symptoms and the patient’s overall health. The doctor will go through everything related to your health, be it your health history or your present health and will recommend the treatment accordingly.
Below are some tests and procedures which will be a part of your treatment.
Surgery is the primary treatment for most oral cancers, especially in the early stages.
It involves the complete removal of the tumor along with a margin of healthy tissue to ensure that no cancer cells remain.
If the cancer has spread to the lymph nodes in the neck, a neck dissection may also be performed to remove affected nodes and prevent further spread.
In cases where large portions of tissue are removed, reconstructive surgery is often done to restore appearance and essential functions such as speech, chewing, and swallowing.
Reconstructive techniques may include skin grafts, tissue flaps, or dental prosthetics, helping patients regain confidence and normal oral activity after treatment.
Chemotherapy uses powerful anti-cancer drugs to destroy rapidly dividing cancer cells in the body.
It may be given before surgery (neoadjuvant therapy) to shrink tumors, or after surgery (adjuvant therapy) to eliminate microscopic cancer cells that might have spread.
In advanced or inoperable cases, chemotherapy helps control tumor growth, reduce pain, and improve quality of life.
Commonly used drugs include cisplatin, carboplatin, and 5-fluorouracil (5-FU), which are often combined with radiation for better results.
Side effects such as nausea, fatigue, or lowered immunity are usually temporary and managed with proper medication and nutrition.
Radiation therapy uses high-energy X-rays or particle beams to kill cancer cells that remain after surgery or to shrink tumors before an operation.
It can also serve as the main treatment for patients who cannot undergo surgery due to medical conditions or tumor location.
Advanced techniques like intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) allow for precise targeting of cancerous tissues while sparing healthy areas such as the jawbone and salivary glands.
Common side effects include dry mouth, mouth ulcers, taste changes, and fatigue, but these are manageable with modern supportive care.
Radiation is often combined with chemotherapy (chemoradiation) to enhance effectiveness in advanced cases.
These advanced treatment options are designed to attack cancer cells more precisely and reduce harm to healthy tissues.
Targeted therapy drugs, such as cetuximab, block specific proteins (like EGFR) that cancer cells use to grow and divide. This slows tumor progression and enhances the effects of radiation or chemotherapy.
Immunotherapy treatments (like nivolumab or pembrolizumab) work by activating the patient’s immune system to recognize and destroy cancer cells more effectively.
These therapies are particularly beneficial for recurrent or metastatic oral cancers, where traditional treatments may not work.
The combination of targeted and immune-based treatments has significantly improved survival rates and long-term outcomes, offering renewed hope for patients with advanced disease.
