 Today I will be discussing with you about the Head and Neck Cancers, its causes, its incidence prevalence, its treatment, newer strategies and all the things about Head and Neck Cancers. As this is almost 30% of all the cancers in the men in India are Head and Neck Cancers. This itself is a heterogeneous group which includes cancers of the oral cavity, oropharynx, nasopharynx, larynx, hyperpharynx and salaried gland tumors. Other part of the Head and Neck tumors they can be like thyroid, they can be esophagus, they can be brain tumors and they can be parathyroid cancers. But because of the different biology and the different treatments of course these are to be discussed separately. Today we will be discussing only about the oral cancer. So oral cancer in India is one of the most common Head and Neck cancer. The reason we all know most common reason is the tobacco consumption which is rampant all across the rural India which is the chewable tobacco and in urban India which is the smoking. Second most common thing is the alcohol consumption, heavy alcohol consumption. And alcohol and tobacco together they increase the chances of this thing more and more. Other risk factors like there can be environmental exposure like the occupational hazards, others are like there are a few infections which are coming up more like the human papillomavirus infection which is generally responsible for the oropharyngeal cancers, others are the upstream bar viruses which are basically responsible for the nasopharyngeal cancers. So forth and so on there are different multiple causes which we cannot like elaborate in such a small time. So coming on to the oral cancer, oral cancer comprises of the cancers of the tongue, the buccal mucosa, the palate, the gingiva, retromolar tricones and outside it can be over the lip. So as we have discussed the causes, so they are now coming on to the treatment diagnosis of these tumors. For the diagnosis most of these tumors they are basically spharmacal carcinomas because the aero digestive tract has a common mucosa and almost 90 to 95 percent of these tumors are spharmacal carcinoma, though they behave differently despite having the same common origin. Second part is for diagnosis we have to do a biopsy. Biopsy can be either an incision biopsy, it can be an excision biopsy, it can be a punch biopsy. So by doing a biopsy we took a small piece of the tumor and sent it for the examination for the confirmation and the diagnosis. Second is once we have confirmed that it is a tumor which is coming from the either from the tongue or palate or somewhere else, we need to do some radiological investigations. That may include CCT or MRI and sometimes we use PET CT also for the whole body scan. Once we are through with this diagnosis and the staging of the disease, here comes the part treatment part. The most common treatment which we entails for oral cavity cancer is the surgical modality. Surgical modality can be in the form of the open surgery and sometimes we can use robotic surgery also but most commonly that is for the oropharyngeal and the laryngeal cancers not for the oral cavity cancer. So other different treatment modalities include radiation oncology and medical oncology and sometimes nuclear medicine too. Radiation oncology is the primary treatment in the oropharyngeal, in the hyperpharyngeal and the laryngeal cancers but in oral cavity surgery is the primary modality and we need adjuvant radiotherapy depending upon the stage of the tumor. Now once we are through with this that we have diagnosed, we have staged, we have treated, now comes the follow-up and the rehabilitation. That is one of the most important part and one of the most neglected part as the and the part of the patient and the part of the doctor. So we have to be very careful about the post-operative rehabilitation that includes speech and swelling and other things regarding the appearance of the patient. Yeah I would like to add, in the end I would like to add two lines on the prevention of this cancer. The most common way of preventing is stopping tobacco consumption. For which we are also, government is also doing, we are also doing some help regarding we have good counseling sessions are also there for stopping tobacco and for stopping alcohol also we have a clinical psychologist in-house who can give good counseling regarding these patients. So we have all the facilities in-house including the PET CT, CET, MRI along with the best of the state of the traditional quality machines and the chemo take care and all the facilities for the surgery, modularities, robotic surgery we are also having in many power hospitals. So if anybody would like to have a consult regarding their problem, they are welcome to do so. Thank you.
