Chapter: 3 - Breast Cancer

Subchapter: 3 - Types of Tumors

Remember, a tumor is a mass of abnormal tissue. There are two types of tumors: those that are non-cancerous, or ‘benign’, and those that are cancerous, which are ‘malignant’.

Benign Tumors
When a tumor is diagnosed as benign, doctors usually leave it alone rather than remove it. Even though these tumors are not aggressive toward surrounding tissue, they may continue to grow, pressing on organs and causing pain or other problems. In these situations, the tumor is removed, allowing pain or complications to subside.

Malignant Tumors
Malignant tumors are cancerous and aggressive, because they invade and damage surrounding tissue. When a tumor is suspected to be malignant, the doctor will preform a biopsy, a diagnostic procedure which we will cover in Sub–Chapter 4.3, to determine the severity of the tumor.

Metastatic Cancer
Metastatic cancer is when cancer cells of a malignant tumor spread to other parts of the body, usually through the lymph system, and form a secondary tumor.

Tumor Grades
Tumor grading is a system used to classify a malignant tumor based upon the severity of the mutation and the likelihood that it will spread. According to the National Cancer Institutes's tumor grading system, there are four grades: low grade (1), intermediate grade (2) and two types of high grades (3 & 4). Grade 1 tumor cells, for example, are the least aggressive in behavior; they still resemble healthy cells and multiply at a slower rate. Higher grade tumors tend to grow and spread more rapidly than tumors of a lower grade.

Tumor grades are not to be confused with cancer stages, which we will discuss in detail in Chapter 5.

In this chapter, we looked at where cancer usually begins, reasons why it grows, how it spreads, the importance of evaluating the tumor for certain receptors, and the difference between benign and malignant tumors.

Now it’s time to get a better understanding of your diagnosis.

      It really depends on the lab. 2 to 3 business days is common. Hopefully your dr will call with the results rather than have you make an office visit. Waiting is the worst, but stay positive. It could just be a fibroid or something. Prayers to you.

      I had to wait 3 days. It varies depending on how busy a lab is. It's the longest days of your life. Stay busy, and stay positive. My doctor told me right from the start "expect it to come back as cancer." It was still a shock when I heard those words. BUT.... Here I am 8 years later,...

My doctor told me right from the start "expect it to come back as cancer." It was still a shock when I heard those words. BUT.... Here I am 8 years later, healthy and cancer free. I am hoping for the best for you. Hang in there and take care. Sharon

      The three that I know of are inflammatory, paget's disease, and metaplastic. These are all RARE and aggressive.
      Other types of breast cancer can be thought of as a more aggressive version because of their grade. The grading is either 1, 2, or 3. One, being slower growing where 3, grows and spreads faster. The other key to breast cancer is early detection. If breast cancer is detected at a later stage, it is more difficult to --corral the bugger.-- NOT impossible, but more difficult. The patient just has to spend more --quality time-- with her oncologist, surgeon, etc.
      The more I learn about breast cancer, the more there is to understand. Science keeps peeling away the layers of the unknown regarding breast cancer. We, as patients benefit from their discoveries.
      Take care, Sharon

      Also it makes a difference if your receptors are positive or negative. But, all are treatable. The kind you have and the postive or negative receptors determine the type of treatment you will advised to have. Good luck to you.

      The thing my sister did that really made it easier for me was to handle all the insurance crap. I signed medical power of attorney to her and she handled all of it. It was a huge relief not to have to worry about that on top of the rest!

      Hormone blocker.... if cancer cells linger, they are starved of the thing that makes them multiply.
