Angelina Jolie was close to tears as she received an honorary Oscar for her humanitarian work at the Governors Awards last night.
Brad Pitt described his partner Angelina Jolie as "absolutely heroic" after the actress revealed she underwent a double mastectomy.
Breast cancer charities warn that all women should be "breast aware" - but what should you look out for?
Pop star Anastacia has undergone a double mastectomy after being diagnosed with breast cancer for the second time earlier this year.
The US singer, whose hits include I'm Outta Love, cancelled her planned European tour in February after the second diagnosis. She was first diagnosed with the disease in 2003.
Anastacia, 45, is in the final stages of recovery following her surgery, and said in a statement to fans that she wanted to bring attention to Breast Cancer Awareness Month, a cause "particularly close to my heart".
"It has been an intense journey but l am feeling great and ready to start the next chapter," she said. "Early detection has saved my life twice. I will continue to battle and lend my voice in anyway I can."
In May, film star Angelina Jolie announced that she had undergone a double mastectomy after learning that she had a 87% chance of developing breast cancer.
Anastacia's announcement follows a report from a leading cancer charity which says that up to 185,000 women could die from breast cancer by 2030 if action is not taken over critical research gaps.
New guidance for doctors will mean women will have access to preventative drugs which dramatically reduce the risk of developing breast cancer.
Last month, Hollywood star Angelina Jolie announced she had a preventative double mastectomy after discovering she was a carrier of the BRCA1 gene, which increases her risk of developing cancer.
Jolie spoke at the time of her happiness that the announcement had generated more discussion about women's health.
Angelina Jolie said she is "feeling great" following her preventative double mastectomy.
Speaking at the premiere of her partner Brad Pitt's movie World War Z in Leicester Square, Jolie said she was "very happy" to see the discussion about women's health since revealing she had undergone the surgery:
Angelina Jolie said Brad Pitt has been "extraordinary" after she underwent a double mastectomy to reduce her risk of developing breast cancer.
Jolie, who discovered she was a carrier of the BRCA1 gene, said she was "feeling fine" during her first public engagement since the operation.
Speaking at the premier of Pitt's new film World War Z in Leicester Square, Jolie said: "He has been extraordinary. He's such a wonderful a man and wonderful father and I'm very, very lucky".
Angelina Jolie and Brad Pitt have arrived in central London for the world premiere of World War Z, at the Empire Leicester Square.
Less than two weeks after actress Angelina Jolie announced she had a double mastectomy to prevent breast cancer, the star's aunt has died from the disease.
Debbie Martin, 61, died in a San Diego, California-area hospital, her husband Ron said today.
The younger sister of Jolie's mother Marcheline Bertrand, whose death in 2007 inspired the surgery that Jolie admitted to having in a May 14 New York Times article, Mrs Martin had the same defective BRCA1 gene as Jolie.
Mr Martin said if his wife had known she had the gene before her diagnosis, "she would have done exactly what Angelina did".
Angelina Jolie announced last week in the New York Times that she had chosen to have a double mastectomy to prevent her getting breast cancer.
TV presenters Kirstie and Sofie Allsopp, whose mother and grandmother had breast cancer, were told they had an increased risk of developing the disease.
Sofie, who had the operation, told Daybreak: "It was a big decision but for me I wanted to do as much as physically possible to stop getting breast cancer myself.
"I felt the most proactive thing I could do was to have a preventative mastectomy so I chose to do that".
Kirstie, who chose not to have a mastectomy said: "The difference between me and Soph is that Soph didn't have children.
"I have got my two children, my two stepchildren, and it could have more impact on my family to take that time out."
Dr Kristi Funk, founder and medical director of the Pink Lotus Breast Centre where Angeline Jolie had a double mastectomy has written a blog about the actress's treatment.
Yesterday, Jolie announced she had underwent the procedure after learning she had a 87% chance of developing breast cancer.
It outlines the main stages of her initial operation through to the end of her surgical journey.
Dr Funk also wrote: "Breast and ovarian cancers take lives every day – knowledge and action can help prevent the premature loss of those who love us, and whom we deeply love in return.
"Like Angelina, I urge women who feel they might have reason to be at risk for a BRCA gene mutation – perhaps because of a strong family history of cancer – to seek medical advice and to take control of their futures".
New York Times columnist Nick Kristof said he has spoken to Angelina Jolie and the actress is "grateful and overwhelmed by the outpouring of public support" following the news she had undergone a double mastectomy.
I've spoken to Angelina Jolie several times in last few days, and she has been so strong, so brave, so determined.
Angelina Jolie also asked me to thank everyone: She is SO grateful and overwhelmed by the outpouring of public support.
And she's thrilled and grateful to see people taking this and having serious, empowering discussions of women's health.
