Mayflower Theatre and Spinnaker Tower will be illuminated in support of secondary breast cancer awareness.

On October 13, the iconic landmarks will join 70 other venues across the UK in lighting up in distinctive pink, purple, and teal colours to raise awareness of secondary breast cancer.

This marks a 25 per cent increase in the number of venues participating compared to last year.

Sam Dixon, CEO of Make 2nds Count, further emphasised the significance of the campaign and said: "These illuminated landmarks represent a beacon of hope for the tens of thousands affected by SBC.

"Through our ‘1000 Truths’ initiative, we also want to bring the personal stories of patients to the forefront, ensuring that every voice is heard, and every life is honoured.

"By shining a light on secondary breast cancer, we hope to raise awareness, build a more empowered community, and ultimately improve the lives of those living with SBC."

The initiative, led by Make 2nds Count, a charity focused on supporting people living with secondary (metastatic) breast cancer, aims to highlight the need for greater awareness, support, and funding for research.

The only day of the year dedicated to raising awareness of secondary breast cancer, October 13, will see these landmarks supporting the "Shine a Light" initiative.

Secondary breast cancer occurs when cancer spreads from the breast to other parts of the body.

Although the disease is incurable, it is treatable, and symptoms can vary from person to person.

An estimated 61,000 people in the UK are living with this condition, which claims 1,000 lives every month. A recent survey revealed that 38 per cent of people did not know what secondary breast cancer was, and 21 per cent did not know what symptoms to look for.

The "1,000 Truths" campaign shares personal stories of patients, families, and healthcare professionals.
