A description of a tumor based on how abnormal the cancer cells and tissue look under a microscope and how quickly the cancer cells are likely to grow and spread . Low-grade cancer cells look more like normal cells and tend to grow and spread more slowly than high-grade cancer cells.

What does the term histological mean?
1 : a branch of anatomy that deals with the minute structure of animal and plant tissues as discernible with the microscope . 2 : tissue structure or organization.
What is a histologic diagnosis?
Histopathology is the diagnosis and study of diseases of the tissues , and involves examining tissues and/or cells under a microscope. Histopathologists are responsible for making tissue diagnoses and helping clinicians manage a patient’s care.
What does histologic changes mean?

How long do histology results take?
It takes around two weeks to get the results for both tests, if you don’t receive the results in over two weeks, it is best to chance this up with your doctor. The wait can be frustrating, but try not to freak out and this won’t help.
Does a biopsy tell you what stage cancer is?
If the cells are cancerous, the biopsy results can tell your doctor where the cancer originated — the type of cancer. A biopsy also helps your doctor determine how aggressive your cancer is — the cancer’s grade.
How is histology done?
The tissue that is studied comes from a biopsy or surgical procedure whereby a sample of the suspect tissue is selected and sent to the laboratory. It is then processed and cut into very thin layers (called sections), stained, and examined under microscopes to characterize the details of the cells in the tissue.
Why is histology important?
Histology is the study of how tissues are structured and how they work . Knowing what a normal tissue looks like and how it normally works is important for recognizing different diseases. It also helps in figuring out what causes certain diseases, how to treat those diseases, and whether the treatment has worked.
What is histology used for?
Histological studies are used in forensic investigations, autopsy, diagnosis and in education . In addition, histology is used extensively in medicine especially in the study of diseased tissues to aid treatment (Black, 2012).
When should a biopsy be done?

How does histology help diagnose an injury or disease?
Histological examination of tissues can help diagnose disease , because each condition produces a characteristic set of changes in the tissue structure. There are such a wide variety of diseases that histology alone usually cannot produce a diagnosis, although in some cases the histological appearance is definitive.
Why does histology take so long?
After the first sections of tissue are seen under the microscope, the pathologist might want to look at more sections for an accurate diagnosis . In these cases, extra pieces of tissue might need processing. Or the lab may need to make more slices of the tissue that has already been embedded in wax blocks.
What is histopathology and why it is important?
Histopathology enables professionals to look for changes in cells that explain the actual cause of the patient’s illness . Pathologists are able to reach a diagnosis by examining a small piece of tissue from various organs. Histopathology is vital as it broadens and progresses treatments options.
What does grade 3 invasive ductal carcinoma mean?
Grade 1 invasive ductal carcinoma cells, which are sometimes called “well differentiated,” look and act somewhat like healthy breast cells. Grade 3 cells, also called “poorly differentiated ,” are more abnormal in their behavior and appearance.
Can histopathology be wrong?
Raab said that a detailed study of the effect of pathology errors by cytologic-histologic correlation has not been done, but others have estimated that 2.3% of cytologic specimens and 0.44% of surgical specimens were wrong , and that 23% of those errors had a significant effect on patient care.
