Sorry to hear you found a lump Zoopet I also had one - best to phone breast care nurses and say but its often scar tissue - mine was scar tissue when they scanned and fairly hard. I was given an ultrasound and told all clear there and then.
London I had lobular as well, 3 of them, it doesn't make too much difference - does grow as a spiders web to start with then lump at end and MRI best at detecting.
Welcome to the newbies. Chemo is tough going and I hated it but it was only for 4 months and it does end. And not everyday is awful. Drink plenty especially pre chemo, eat little and often can help, be careful to avoid infections - use a digital thermometer to take temp twice a day or immediately if feel ill and immediately call chemo line even if middle of night if goes out of range that way it helps avoids effects becoming serious. I never got serious side effects apart from steroids and also got neuropathy. Report neuropathy as well - mainly on the taxols. Sickness etc there are so many meds let them know and they can change meds, also don't be afraid to have less sickness meds if they are causing stomach pain / indigestion - I need 1 to 2 ondansetron per week they gave me 6 and told me to take 6. Steroids check with the oncologist if badly affected or chemo line - mine were significantly reduced but they are to stop allergic reactions so they like them at start. Keep a daily diary of symptoms can help, gives a pattern for each cycle. Its common to be terrified - I found it helpful to view it as 1 chemo and see how it went and I was terrified throughout but you just need to turn up - they are used to people crying / panic attacks etc. You can also request meds for anxiety but when people say cancer patients are brave its really just doing it as its that or death and many of us were absolutely terrified but it does end. And whenever you get chance for a nice day out take it, in a 3 week cycle generally last week, weekly Pax is more meh throughout but sometimes they give you a break due to neuropathy and then take your chance to go away. I went to see puffins.
Worth seeing dentist pre chemo, probably private given lack of nhs and get any work needed done and extra fluoride toothpaste, quite brutal on teeth but mine are fine. Eyesight can also be affected, anything really let them know. With taxols worth using ice socks and ice gloves (Amazon have them if google chemo plus those terms) and take a coolbox from a camping or similar shop - can use ice or frozen peas instead. Cold cap is an option for some not for me but can help with hair loss. I found surgery, radio and hormone tablets fairly easy but chemo and the tests for cancer hell on earth but once through a very difficult year you do get to a new normal. I am now 2 years all clear and seen my 2 kids to be 17 and 18, one into Oxford Uni, the other really struggled and is SN but am back taking holidays - last one Borneo with my daughter, and have just got a new job which I love so good things can happen again. Obviously there's a lifetime risk of reoccurrence but I tend not to think about that, I don't want cancer taking any more of my life through worry and I am going to enjoy life now until it returns. I would say the good thing is you meet lots of lovely people, there is lots of support and sympathy and it was like the ultimate exposure therapy - hellish to get through at times (mainly mentally) but now I am much tougher and will do things now I would never have been brave enough to do before. I am back to best fitness ever been at and memory back to normal, do have some neuropathy and hair is still a lot shorter than before but finally better. So curly before. I have DIEP surgery on 13th. I also found a chemo buddy useful during chemo, I had a couple of people going through chemo same time and we moaned together - find someone similar attitude to you, I was a moaner. So it was lots of this week was rubbish, but just having someone who got it helped. One was from here via PM and other was from another cancer forum. The charity SomethingToLookForwardto was great, gave us a free week on Cornish coast in July. And financial help if needed (I got ESA, can also get PIP) Macmillan can help, and apply as soon as you feel up to it, can take a while but gets backdated.
