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's not that bad really! The only thing is that my parents think it is highly unlikely for a 16 year old to have breast cancer so they aren't really worried. They're in no hurry or anything that's all. It's just I had to wait quite sometime to tell them and almost only a week or two for the ultra sound. They even felt like there was something wrong with the appointment so they made me another one with a different doctor. It's not their fault that there isn't much hospitals for this here. There is a really big hospital that specializes with cancer which they made the new appointment with. I don't have any symptoms or anything much so... That's the only reason they're not in a hurry. I did talk to my school counselor and I felt much better! The only reason 'I'm dying' is because I'm thinking too much because of the waiting. I posted that question when my mind was in the dark side. Please don't take it that way. I'm having the ultrasound in 3 or 4 days. That's all there is to that post. Thank you all for caring so much! But really my mind will be set at ease in a couple of days!

      dcis is stage 0, or pre cancer. dcis can be ductal or lobular. some docs now consider dcis cancer and others pre cancer. listen to your intuition, get 2nd opinion if you aren't happy with what your doc has told you so far.

      Ductal carcinoma in situ (DCIS) is the most common NON invasive breast cancer! Ductal means is in the milk ducts. In situ, or encapsulated, means the tumor is in it's early stages, inside it's capsule. Better to understand is like a bubble that didn't rupture yet so the tissue around is, probably, contaminated!

      I would get it checked out since this is something new. Only a doctor can tell you what it is. The likelihood is that it probably is not cancer, but you need to know.

      It probably isn't cancer but my rule of thumb is always....if something isn't gone or looking better in a week, I get myself to the doctor. It really sounds like a pimple.
