Good morning, I am Dr Dinesh Singh I am director of Radiation Oncology at Max Hospital, Vaishali. Today we are going to discuss about cancer, the cancer is a group of about 100 disease different diseases and it is basically the cells they start developing, multiplying and then they do not stop first they grow locally and there and then they spread out to different parts and what are the different symptoms of the cancers, well it depends upon which part of the body the cancer is developing like we are discussing about the brain tumors that the patient might have difficulty in vision, he may be having headache, he may be having vomiting or he may be having fits. Then to further investigate we need do a contrast study of the MRI then we diagnosed and then we keep recording it. For head and neck cancers like they can wear ulcer or a soar which doesn't heal, there can be a change in the voice the person might have difficulty in swallowing or so these are the early symptoms of cancers originating into the head and neck area. Then we further investigate we take a biopsy and then we diagnose the patient. For breast cancer, the earliest symptoms is a painless lump usually in Cancer in early stages pain is not there, so whenever there is a lump in a breast it should be investigated to allowed cancer. More than 90% of the lump in the breast on cancerous but it should be evaluated and cure, when we come to the lung cancer the common symptom is a mild cough. So any cough which is not getting the cure for more than two weeks it should be taken seriously it can be tuberculosis, it can be cancerous, so it has to be evaluated and investigative. Talking about the GI cancers of the intestinal cancers, well it present like indigestion or the patient is not getting well some might discomfort in the abdomen. So any problem persisting more than 2 weeks should be investigated by ultrasound, by endoscopy and then we do it. Carcinoma of the rectum and anal canal usually present with a bleeding associated with the stools or without stool should not be confused with the piles because they have the same presentation. So any problem persisting for more than 2 weeks is the thumb rule has to be investigated diagnosed and they have to be treated. Once we see that there is a problem then what we do we have to do an investigation and the first investigation is the biopsy many times a general people they have a false notion that if a biopsy is done then cancer will spread, well it is absolutely wrong. The biopsy is a must and it does not spread cancer. Thank you.
