Yes, it is possible to have cancer and not know what kind. This is because cancer can be difficult to diagnose and it is not always immediately obvious what type of cancer someone may have. Diagnosing cancer involves a range of tests, which can include biopsies, imaging tests, and blood tests. However, some types of cancer may not show up on any of these tests or may not be easy to identify.
What Tests Are Used To Diagnose Cancer?
When diagnosing cancer, doctors will often use a range of tests to identify the type of cancer someone has. These tests can include physical exams, imaging tests (such as CT scans and MRI scans), and biopsies. Biopsies involve taking a sample of tissue from the affected area and testing it in a laboratory to determine if cancer cells are present. Blood tests may also be used to help diagnose cancer.
How Can Cancer Go Undiagnosed?
Cancer can go undiagnosed for a variety of reasons. For example, some types of cancer may not be visible on imaging tests or may be difficult to detect. In addition, some cancer cells may not be detected in a biopsy or may not show up on blood tests. Additionally, some people may have cancer but may not experience any symptoms, which can make it difficult to diagnose.
What Are The Signs Of Cancer?
The signs and symptoms of cancer vary depending on the type of cancer and where it is located in the body. Common signs and symptoms can include:
- Unexplained weight loss
- Unexplained fatigue
- Unexplained fever
- Unexplained night sweats
- Unexplained pain or discomfort
- A lump or thickening in the skin or other parts of the body
- Unusual bleeding or discharge
- Changes in bowel habits
If you experience any of these symptoms or notice any changes in your body, it is important to speak to your doctor as soon as possible. They can help determine if you have cancer or if there is another underlying cause.
