List of Treatments


  • Chemotherapy for Solid Malignancies: Chemotherapy for solid malignancies is a treatment that uses drugs to destroy cancer cells. Because the chemicals affect the entire body, it can destroy cancer cells in the tumor as well as any cells that have broken out of it and traveled through the blood or lymph to another place


  • Radiotherapy: High doses of radiation are used in radiation therapy, commonly known as radiotherapy, as a cancer treatment to eradicate cancer cells and reduce tumor size. As with x-rays of the teeth or shattered bones, radiation is utilized at low levels in x-rays to view inside the body.


  • Chronic Lymphocytic Leukemia (CLL): In the case of chronic lymphocytic leukemia, an excessive number of lymphocytes are produced by the bone marrow. Leukemia can have an effect on red blood cells, white blood cells, and platelets. Fatigue and enlarged lymph nodes are two indicators of chronic lymphocytic leukemia. The doctor frequently recommends surgical procedures to treat this disorder.


  • Cytology Guided by Ultrasound: This process consists of an image guided by ultrasound to perform cytology test that employs ultrasound technology to assist Specialist Radiologists in the performance of needle biopsies. The Specialist Radiologist uses ultrasound equipment to find and guide a specific needle to the proper place in the body during an Ultrasound-guided procedure.

  • IMRT: Conformal radiotherapy includes intensity-modulated radiation (IMRT). With conformal radiotherapy, the radiation beams are precisely shaped to fit the cancerous tissue. A linear accelerator (LINAC), a common radiation device, is used for IMRT.


  • Tumors and Cysts: A cyst is a sac that can contain air, liquids, or other substances. Any portion of the body, including bones, organs, and soft tissues, can develop a cyst. Most cysts are noncancerous. Tumors are defined as any unwanted mass of cells or inflammation in the body. As compared to cysts, tumors are cancerous. Tumors and cysts are removed by surgery, often performed under highly observed conditions.


  • Stem Cell transplantation is a process in which a patient receives healthy stem cells that are replaced with damaged stem cells that were caused by radiation or high-dose chemotherapy treatment. The competent stem cells may come from the patient's blood or bone marrow or from a donor who is identical or similar.


  • Oral Cancer Treatment: Oral cancers can form on the tongue, the tissue that covers the mouth and lips, beneath the tongue, at the base of the tongue, and in the neck area towards the back of the mouth. Treatment for oral cancer includes a combination of surgery, radiotherapy, or chemotherapy. 


  • Minimally Invasive Surgery: Minimally invasive surgeries are those surgical procedures that do not require any kind of major incisions in the body. To perform the procedure, tiny surgical instruments are placed into additional incisions.


  • Giant Cell Tumor Treatment: Curettage is the most commonly utilized surgical treatment to treat giant cell tumors. Special devices are used to remove the tumor from the bone during curettage, after which a bone transplant is performed. The opening is filled with a bone transplant after curettage to strengthen the bone.


  • PICC Line Insertion: This procedure uses a type of catheter to access the large veins in your chest to provide intravenous supply that can be used for a long time or to provide medications that should not be administered peripherally.


  • Ewing's Sarcoma Treatment: Ewing's sarcoma is a type of tumor that develops from a specific type of bone or soft tissue cell. Treatment options for Ewing sarcoma may include a combination of chemotherapy with minor surgery or palliative radiation treatment for bone tumors to reduce symptoms. 


  • Melanoma Treatment: Disorders of the tumor cells are also known as melanoma. The primary therapy for melanoma is surgical removal of the original melanoma on the skin, known as excision. Most melanomas are discovered when they are less than 1.0 mm thick, and minimally invasive treatment is frequently required in this situation.


  • Hemophilia: A genetic bleeding illness called hemophilia causes the blood to clot improperly. This may result in both spontaneous bleeding and bleeding after injury or surgery. The basic method of treating severe hemophilia is to replace the necessary clotting factor via a tube in a vein.
