Which of the following denotes cancers of blood-forming organs?

Cancers of blood-forming organs are generally classified under **hematologic malignancies** (also known as **hematological cancers**). This category includes: 1. **Leukemia**: Cancers that originate in the bone marrow and result in high numbers of abnormal white blood cells. 2. **Lymphoma**: Cancers that develop in the lymphatic system, particularly in lymph nodes. 3. **Multiple Myeloma**: A cancer of plasma cells in the bone marrow. These malignancies impact the blood, bone marrow, lymph nodes, and other components of the hematopoietic (blood-forming) system. If you're selecting from multiple-choice options, the best general term to denote cancers of blood-forming organs is **hematologic malignancies**. However, if specific types are listed as options, **leukemia** would be a primary example. **Answer:** Hematologic malignancies (hematological cancers) denote cancers of blood-forming organs.
