Locally advanced: Definition, Uses, and Clinical Overview

Locally advanced is a clinical term that describes a cancer that has grown beyond where it started but has not spread to distant organs. It often means the tumor involves nearby tissues, structures, or regional lymph nodes. It is commonly used in staging discussions, imaging reports, and oncology treatment planning. The exact meaning can vary by cancer type and stage.

Secondary tumor: Definition, Uses, and Clinical Overview

A Secondary tumor is a tumor found in a new location after cancer cells spread from an original (primary) cancer. The term is commonly used in oncology to describe metastasis, meaning “spread” to another organ or tissue. Sometimes people also use “secondary” to describe a new, separate cancer that develops later (a second primary cancer). Because the wording can be confusing, clinicians often clarify what “secondary” means in each case.

Metastasis: Definition, Uses, and Clinical Overview

Metastasis is the spread of cancer cells from where they started to another part of the body. It is commonly discussed in cancer diagnosis, staging, and treatment planning. A metastatic tumor is made of the same cancer type as the original (primary) tumor. Metastasis is a key concept in oncology, pathology, radiology, and cancer surgery.

Myeloma: Definition, Uses, and Clinical Overview

Myeloma is a blood cancer that starts in plasma cells, a type of white blood cell found in the bone marrow. It is commonly used to describe **multiple myeloma**, the most frequent form. Myeloma is discussed in oncology, hematology, radiology, pathology, and supportive cancer care because it can affect bones, kidneys, blood counts, and immunity. Care often involves both treating the cancer and preventing or managing complications.

Leukemia: Definition, Uses, and Clinical Overview

Leukemia is a cancer that starts in blood-forming tissues, most often the bone marrow. It leads to abnormal blood cells that can crowd out normal blood production. Leukemia is a clinical diagnosis used in oncology and hematology to classify blood cancers and guide care. The term is commonly used in clinics, hospitals, and labs when blood counts or marrow tests suggest a blood-cell malignancy.

Sarcoma: Definition, Uses, and Clinical Overview

Sarcoma is a type of cancer that starts in connective tissues such as muscle, fat, nerves, blood vessels, cartilage, or bone. It is commonly discussed in oncology, surgery, radiation therapy, and pathology because diagnosis and treatment often require multiple specialties. Sarcoma care is used in both adult and pediatric cancer settings, depending on the subtype and the patient’s age.

Carcinoma: Definition, Uses, and Clinical Overview

Carcinoma is a type of cancer that starts in epithelial cells, the cells that line organs and body surfaces. It is one of the most common categories of cancer used in pathology and oncology. Clinicians use the term Carcinoma to describe many cancers of the skin, lung, breast, prostate, colon, and more. Carcinoma is a broad label that is refined by the organ involved and the tumor’s microscopic features.

Cancer: Definition, Uses, and Clinical Overview

Cancer is a group of diseases in which abnormal cells grow and can invade nearby tissues. It can start in almost any organ or tissue, including blood-forming tissues. It is commonly used as a diagnosis in medicine and as an umbrella term in oncology care. People may also use the word to describe treatment, services, and long-term follow-up after therapy.
