![]() You may need an MRI or PET scan while wearing the mask to improve accuracy of the radiation field. You may receive a contrast solution during the scan. We will project laser lines on the mask and draw this field on the mask to ensure that you will be in an identical position during all treatment sessions. You will be wearing the mask during the scan. You will get a CT scan to prepare for your treatment. There are plenty of holes in the mask to allow you to breathe, hear, and see. ![]() The plastic will be heated and placed on your face so the mask will have the same contours as your face. The number of sessions you will receive depends on your personal situation and can vary between 1 and 16.įor treatment of cancer in the head and neck region we will prepare by making a mask, which will ensure that you cannot move during the treatment. We will make the mask out of pliable plastic at our moulage room. This will shrink it and halt tumor growth, but the treatment cannot cure you. Radiation can be given as a palliative treatment to alleviate the symptoms when the cancer has developed or spread, or if the tumor causes a lot of discomfort. The total amount of sessions you will have depends on the results of your pathological tests and can vary between 23 and 35. If we suspect that some tumor cells remained after your surgery, we will deliver radiation after your surgery. You will receive 35 radiation sessions and will be given 7 doses of immunotherapy. The cancer cells will be more sensitive to the radiation treatment, which can increase its effects. Cetuximab is a drug that activates the immune response against the cancer cells. You will receive 35 radiation sessions, combined with 3 chemotherapy sessions. It can make cancer cells more sensitive to radiation treatment, which will increase the effectiveness of the treatment. Cisplatin kills the cancer cells and halts cell division. This treatment uses drugs called Cisplatin or Cetuximab. We call this chemoradiation or bioradiation. In some cases we combine the radioherapy with chemotherapy or immunotherapy. Radiotherapy aimed at the head and neck area usually consists of 35 treatment sessions over a period of 6 to 7 weeks. Common types of head and neck cancer are: the tongue, the base of the tongue, the roof of the mouth, the throat cavity and the vocal cords. Now the tree is unbalanced, so it is rotated to make it again balanced.Head and neck cancer includes tumors that develop in any kind of tissue in the head and neck area. Sunday is inserted to the right of Saturday (Sa After that, insert Saturday, to the left of Thursday (S Note: In case if we don’t remember the rules of rotation of AVL tree, still it can be balanced we just need to remember that: Left node 3 5 Now if the balance factor, is checked it can be seen that the balance factor of Tuesday is 2 so it is unbalanced, so there is a need to rotate the tree to make it balanced. The next step is to insert Monday to the left of Tuesday as it is alphabetically smaller(M M).So according to the given order, let’s insert Tuesday, as it has no node so it has a balance factor of 0.Check the Balance Factor: The balance factor should always be -1, 0, 1 if not then there is a need to rotate the tree accordingly. ![]() Following are two basic operations that can be performed to re-balance a BST without violating the BST property (keys(left) < key(root) < keys(right)).
