Ductal Carcinoma in Situ (DCIS) 

Ductal carcinoma in situ (DCIS) is the most common type of non-invasive breast cancer. Ductal means that the cancer starts inside the milk ducts, carcinoma refers to any cancer that begins in the skin or other tissues (including breast tissue) that cover or line the internal organs, and in situ means "in its original place." DCIS is called "non-invasive" because it hasn't spread beyond the milk duct into any normal surrounding breast tissue. DCIS isn't life-threatening, but having DCIS can increase the risk of developing an invasive breast cancer later on.

Embryonal Tumors, Central Nervous System, Childhood

Central (CNS) embryonal tumors may begin in embryonic (fetal) cells that remain in the after birth.

Central nervous system (CNS) embryonal tumors form in embryonic cells that remain in the after birth. CNS embryonal tumors tend to spread through the cerebrospinal fluid (CSF) to other parts of the and spinal cord.

The tumors may be malignant or not.

Endometrial Cancer

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs.

Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer.

Esophageal Cancer

Esophageal cancer (or oesophageal cancer) is arising from the —the food pipe that runs between the throat and the stomach. Symptoms often include and weight loss. Other symptoms may include , a , (glands) around the , a dry cough, and possibly coughing up  or vomiting blood.

Esthesioneuroblastoma, Childhood

Esthesioneuroblastoma or olfactory neuroblastoma is a rare tumour of neuronal origin (14) arising in the olfactory epithelium of the nasal vault. It is more frequently encountered in adults. Conventional treatment, consisting of surgical resection and/or radiation therapy, does not prevent local recurrence. The prognosis in cases of extensive disease is worse than in those of limited disease (5, 10). Good results in childhood neuroblastomas have been obtained with chemotherapy (7, 8). Various trials have therefore been proposed for certain olfactory neuroblastomas. The promising results encouraged us to use chemotherapy as the treatment of choice in a child of 4 suffering from an advanced form of the disease, given the consequences of surgery of radiotherapy at that age. 

Ewing Sarcoma

Is a primary bone cancer that affects mainly children and adolescents. It's one of a group of cancers known collectively as the Ewing family of tumors -- ESFT or sometimes just EFT. It's the second most common in children, but it's also relatively uncommon. It accounts for only 1% of all childhood cancers. Although it can occur at any age, it very rarely occurs in adults over the age of 30.

Because many illnesses can cause the same symptoms as Ewing's sarcoma, it's sometimes missed in its early stages. But early diagnosis and treatment is important. If found early enough, before it spreads to multiple organs, Ewing's sarcoma can be treated successfully in 50% to 75% of cases.

Extracranial Germ Cell Tumor, Childhood

Germ cells are reproductive cells that develop into testicles in males and ovaries in females. Sometimes these cells travel to other areas of the body, such as the chest, abdomen, or brain, and may turn into a rare type of cancer called germ cell tumor. This summary covers germ cell tumors that occur extracranially (everywhere but in the brain).

Extracranial germ cell tumors can be benign (not cancerous) or malignant (cancerous). Most germ cell tumors are benign and are very rare in children younger than age 15. Germ cell tumors of early childhood have biological characteristics which are different than those that occur in adolescents and young adults. The location of the tumor and the age of the child make a difference in the prognosis (chance of recovery) and in how the tumor is treated.

Extragonadal Germ Cell Tumor

Extragonadal germinal cell syndromes are rare tumors that predominantly affect young males. Literature suggests that the only known risk factor for extragonadal germ cell tumors (EGCTs) is (47XXY), which is associated with mediastinal nonseminomatous germ cell tumors.They are characterized by their location on the midline from the pineal gland to the coccyx. In extragonadal germ cell tumors, no evidence of a primary is present in either the testes or ovaries by radiologic imaging or physical examination. Extragonadal germ cell tumors produce a rich symptomatology and may reach large volumes if they arise in silent areas. Histologically, they mirror their gonadal counterparts with which they share the same chemosensitivity and radiosensitivity. Modern approaches to diagnosis and treatment can result in high rates of long-term survival and even cure.

 Eye Cancer 

Cancer of the eye is uncommon. It can affect the outer parts of the eye, such as the eyelid, which are made up of muscles, skin and nerves. If the cancer starts inside the eyeball it's called intraocular cancer. The most common intraocular cancers in adults are melanoma and lymphoma. 

Fallopian Tube Cancer

Fallopian Tube Cancer. Fallopian tube cancer, also known as tubalcancer, develops in the fallopian tubes that connect the ovaries and the uterus. It is very rare and accounts for only 1 percent to 2 percent of all gynecologic cancers. 

Fibrous Histiocytoma of Bone, Malignant, and Osteosarcoma

Usually starts in osteoblasts, which are a type of bone that becomes new bone . Osteosarcoma is most common in adolescents. It commonly forms in the ends of the long bones of the body, which include bones of the arms and legs. In children and adolescents, it often forms in the bones near the knee. Rarely, osteosarcoma may be found in or in the chest or.

Osteosarcoma is the most common type of . (MFH) of bone is a rare of the bone. It is treated like osteosarcoma.
