Which type of cancer is characterized by the formation of cysts and happens commonly in which organ?

  1. Breast cancer

  2. Ovarian cancer

  3. Prostate cancer

  4. Liver cancer

The correct answer is: Ovarian cancer

The correct choice indicates ovarian cancer, which is known for the formation of cysts and commonly affects the ovaries. Ovarian cancer can present with various types of ovarian cysts, some of which may be benign while others can be malignant. These cysts develop in the ovaries and can range in size and complexity, often leading to symptoms that may prompt further investigation. In contrast, while breast cancer can also present with cysts (such as in the case of benign breast disease), it is primarily characterized by the presence of tumors rather than cystic formations. Prostate cancer typically presents as nodules or tumors in the prostate gland rather than cysts. Liver cancer predominantly arises from liver cells or can be secondary to metastasis from other cancers and does not typically feature cyst formation as a primary characteristic. Therefore, the association of cyst formation with ovarian cancer distinctly supports the accuracy of the correct answer.
