How Urgent Is Surgery for Breast Cancer?

 Does time to surgery affect breast cancer outcomes?

There’s always going to be some amount of time between diagnosis and surgery. This is because a healthcare team will do preoperative tests to better understand your cancer. It can also sometimes take time to schedule your surgery.

There’s no standard for how soon you should have surgery after a breast cancer diagnosis.

However, it’s possible that delays in having surgery can affect breast cancer outcomes. A longer delay could potentially lead to the growth or progression of your cancer.

A 2016 studyTrusted Source looked at time to surgery in 94,544 people with breast cancer. Time to surgery was divided up into five 3-month intervals:

less than 30 days

31 to 60 days

61 to 90 days

91 to 120 days

121 to 180 days

The researchers found that overall survival was lower with each increasing delay interval. They noted that while preoperative evaluations are important, a shorter time to surgery should be pursued, if possible.

How long is too long?

Because time to surgery can affect outlook, you may be wondering how long is too long to wait. Generally speaking, it’s ideal to keep the time to surgery as short as you can while considering necessary preoperative tests and decision making.

Research on this topic is conflicting. For example, studies from 2017Trusted Source and 2022 found that the outlook for people with breast cancer wasn’t affected until time to surgery surpassed 60 days.

A 2018 reviewTrusted Source examined studies on the time to treatment and how outlook was affected. Based on their review, the author noted that a time from diagnosis to surgery of less than 90 days was optimal for outlook.

A 2020 studyTrusted Source that looked at the effects of time to first breast cancer treatment supports this. It concluded that a longer time to first treatment, defined as 31 to 90 days, would promote more thorough diagnostic testing and decision making without compromising survival.

 Many treatments that enhance the appearance of your hair can actually damage it, causing your hair to become dry and brittle. Follow these dermatologists’ tips to prevent dry, brittle hair: When dyeing your hair, stay ‘on shade’. Choose a dye within three shades of your natural color. Typically dyeing hair darker is better than lighter. Lightening your hair more than three shades requires higher volumes of peroxide, which causes more hair damage. Test store-bought hair color before using. Follow manufacturer’s instructions. If you develop a rash or redness, swelling, burning or itching, you are having an allergic reaction to the die. Do not dye your hair and consult your dermatologist for further allergy testing. Protect your hair from the sun. The sun can make your hair weak, dry, rough, faded and brittle. This is especially true if you dye, bleach or perm your hair. Wear a wide-brimmed hat when you go outside. Use caution when perming hair to prevent long-lasting damage. Set a timer

Does Breastfeeding Prevent Breast Cancer?

 How does breastfeeding lower your risk of breast cancer? Breastfeeding is a protective factor for breast cancer. It’s unclear exactly why this is the case. However, a combination of the following factors is likely at work: Breastfeeding promotes changes in breast cells that may make breast cancer less likely to occur. The hormonal changes that happen during breastfeeding can delay the return of your period, meaning you’re exposed to less estrogen while breastfeeding. Long-time exposure to estrogen raises breast cancer risk. It’s more likely that people who are breastfeeding engage in healthy lifestyle choices, such as eating a balanced diet, avoiding alcohol, and not smoking. Now let’s look at what some of the research on breastfeeding and breast cancer risk has found. Research into breastfeeding and breast cancer risk Older research from 2002Trusted Source involving data from 47 studies across 30 countries found that the risk of breast cancer decreased by 4.3% for every 12 months of

Though it is part of our routines to make sure to protect our skin before heading out for a fun, sun-filled summer day (and every day!), rarely do we give our hair the same attention.
