Treatments of Different Cancer

story

Treatment of Nasopharyngeal Cancer

Tumor has not spread beyond to lymph nodes

  • Radiation therapy aiming at the tumor and nearby lymph nodes
  • Tumor has spread to lymph nodes

  • Chemoradiation: radiotherapy and chemotherapy are given simultaneously. Drug used usually is cisplatin. Sometimes 5FU is also added. Radiation is usually external beam and IMRT(intensity modulated radiation therapy)
  • Induction chemo followed by chemoradiotherapy

    Treatment of Breast Cancer

    Cancer is confined to the inside of the milk duct

  • Surgery
  • Targeted therapy
  • Hormonal therapy
  • Tumor is relatively small with no metastasis or a small tumor that has spread only to one or two sentinel nodes

  • Breast conserving surgery with or without wire localization usually a lumpectomy
  • May need radiation(external beam: accelerated or internal radiation) therapy following surgery
