Speedy, have you been Googling? Move away from that Google! It has many fine qualities as a search engine if you are after a nice recipe for Spaghetti Bolognese or pictures of Brad Pitt (as I understand it). But as a tool to tell you your odds, it's less accurate than standing at the pub exit last thing on a Friday night and asking the people who are staggering home. Google brings up the most common answers. They are most common because they are based on the oldest and most useless data. Almost everything has changed in Breast Cancer in the last couple of years (new genetic stuff, targeted personalised medicines etc) and the new treatments are so new that the statistics aren't anywhere online at all. Worse still, some teams had a negative attitude to TNBC in older women and just didn't even bother with chemotherapy and radiotherapy (!). Unsurprisingly, more of their patients had a bad outcome. So...that's why some of the stuff online ended up looking really negative.
What we know for sure is that TNBC (Triple Negative Breast Cancer) is a rudely behaved one, but it's also one that 'runs out of steam' fast. Rudely behaved cancers are also thirsty and drink up chemotherapy fast. As a consequence, they cop it fast, too. So chemotherapy tends to work better than for other people.
What the team will watch for is how effective the chemotherapy is. In some people, it doesn't work. Those are the head-scratching cases for a team. They will use surgery and radiotherapy to do the job instead and look to get really good 'clear margins' round the lump when they do surgery. If they think they've got it all out, that's a very good sign. They will also look for any of it creeping back, and then try out some of the new potions that are in trials. (Some are looking good in the early trials - I watch the research papers)
In some cases it shrinks the lump quite a bit. That's also good. They can then target it with surgery, radiotherapy and other potions (if available) and improve the odds further.
In a good number of cases, the lump disappears completely after chemotherapy. This is called pCR. This is where the team does the Dance of Hurrah in the hallways and you're pretty much guaranteed a long and happy life.
So, each thing you're told about your breast cancer at the start doesn't exactly make it better or worse as an outcome - it is information for your team so that they know which treatments to use.
Hope that helps....
