Breast Cancer Growth Rate

I came across this article recently and it was really shocking to me. I have always understood that breast cancer grows by cell division, but I had no idea of the timing from when it starts to when you can feel a lump in the breast like I did. I know that the information below is scary, but I am posting this to inform my readers because I truly believe that when it comes to breast cancer, early detection and information are key. If you won’t listen to me, listen to a doctor who makes it clear in the article below that a yearly mammogram is so incredibly important. As you know, I also believe that a monthly self-exam between mammograms is just as important. I don’t want anyone to go through what I have been through in the last 18 months, so if I can help just one reader understand the importance of mammograms then I have done my job.

Speaking of mammograms…my last mammogram was before my first surgery in April 2019. Now that I am over six months out from my last radiation treatment it is time to finally have a mammogram done to make sure that cancer has not come back. My surgeon explained that we couldn’t have a mammogram done any sooner than now because the radiation causes the images to look cloudy. So, next Monday I will have the mammogram done that my surgeon ordered back in February. I am scared, to say the least, but I am trying to have faith that all of the chemo and radiation treatments killed any tiny cancer cells that may have been too small to detect after my first surgery.

Ask an Expert: Breast cancer growth rate

From the expert staff of breast cancer research at the Robert W. Franz Cancer Research Center at Providence Portland Medical Center:

Like a lot of cancers, breast cancer grows by simple cell division. It begins as one malignant cell, which then divides and becomes two bad cells, which divide again and become four bad cells, and so on. Breast cancer has to divide 30 times before it can be felt. Up to the 28th cell division, neither you nor your doctor can detect it by hand.

With most breast cancers, each division takes one to two months, so by the time you can feel a cancerous lump, cancer has been in your body for two to five years. It can certainly seem like a lump appeared out of nowhere – especially if you or your doctor have recently examined your breasts and not felt anything suspicious – but in reality, cancer has simply doubled that one last time necessary to be noticeable. By the time you can feel it, a breast tumor is usually a little more than one-half inch in size – about a third the size of a golf ball. It has also been in your body long enough to have had a chance to spread.

This sounds scary, but what it really underscores is the importance of regular mammograms. These screening tests can usually detect breast cancer when it’s about one-quarter inch in size or smaller – a year or more before it would be detectable by hand. Mammograms also make possible the early diagnosis of some pre-cancerous conditions and early-stage cancers that appear as tiny calcifications (microcalcifications) on mammography but aren’t detectable by physical examination.

It’s important to realize that there are two types of mammograms:

screeningmammogram is performed in cases where there isn’t any known problem. This type of mammogram is used for annual exams.

A diagnostic mammogram is performed when there is a known problem that requires careful evaluation. Diagnostic mammograms provide much more extensive images than screening mammograms, such as views from additional angles and compression, or blow-up, views. Often an ultrasound will be done in addition to the mammogram if there is a palpable lump. Make sure you receive a diagnostic mammogram if you’ve found a lump.

Once a breast cancer gets big, every doubling is significant. If you find a lump, see your doctor as soon as possible. Don’t settle for just a mammogram if the mammogram doesn’t find anything. The next step should be a screening ultrasound, and if those results are indeterminate you need to get a biopsy. Ask your doctor for these tests if he or she doesn’t schedule them.

Breast Cancer Glossary: 41 Terms You Should Know

When I was first diagnosed with breast cancer it was unimaginably overwhelming in so many ways. My head was spinning with questions and fears and like many newly diagnosed patients, I felt like I needed to quickly learn a new language. Little by little I began to understand my diagnosis and what it meant for me as a breast cancer patient. Now, 16 months later, I have come across all of these terms either through my own experiences, discussions with my doctors or by reading the endless sources of information that I have discovered along the way. In the beginning of my journey it would have been so helpful to have all of the information below in one place for me to reference. I hope by sharing this article I am able to help answer some of the questions you might have as a breast cancer patient or a caregiver to a breast cancer patient.

At the bottom of this article, Monica suggests writing your cancer story basics using this guide. I am finding that quite often people will ask me for this information whether it is in a new forum that I have joined or during a conversation I am having with someone new. I have included my cancer story basics here in this blog post and on my “About Me” page.

My Cancer Story Basics: I was Dx at age 51 w/ ER/PR+, HER2-, IDC. I have had ACT, Rads, and I am on a 10 yr plan w/ HT, Anastrozole. My cancerversary is the date of Dx on February 25th, 2019. I have had a partial mastectomy, port-a-cath insertion, reconstruction w/reduction mammoplasty and insertion of breast prosthesis following reconstruction.

Utterly overwhelmed is how I felt when I faced the uncertainty and devastation of my breast cancer diagnosis 5 years ago.

I dove into online communities to connect, observe, research, and be heard. When I did, I was lost on some of the language. There were so many terms, acronyms, and abbreviations to learn.

Some things that now seem obvious to understand weren’t while dealing with a brain processing the new trauma of my cancer diagnosis.
