Immunotherapy: Harnessing the Body’s Defence Mechanisms
One of the most promising areas in breast cancer treatment is immunotherapy. This approach leverages the body’s immune system to recognise and attack cancer cells. Recent clinical trials have shown that immunotherapy can be particularly effective for triple-negative breast cancer, a subtype that is often resistant to traditional treatments.
Checkpoint Inhibitors
Checkpoint inhibitors are drugs that help the immune system recognise cancer cells. By blocking proteins that prevent immune cells from attacking cancer, these inhibitors allow the body’s defence mechanisms to target tumours more effectively. Drugs like Pembrolizumab have shown encouraging results in clinical trials, improving survival rates for certain breast cancer patients.

Targeted Therapy: Precision Medicine at Its Best
Targeted therapies focus on specific molecules and pathways that are crucial for cancer cell survival and proliferation. By interfering with these targets, such treatments can inhibit tumour growth while minimising damage to healthy cells.
CDK4/6 Inhibitors
Cyclin-dependent kinases 4 and 6 (CDK4/6) are enzymes that play a vital role in cell division. Inhibitors like Palbociclib have been approved for treating hormone receptor-positive, HER2-negative advanced breast cancer. These drugs have extended progression-free survival, offering new hope for patients with this subtype.
PARP Inhibitors
Poly (ADP-ribose) polymerase (PARP) inhibitors are showing promise, especially for patients with BRCA1 or BRCA2 mutations. By blocking PARP enzymes, these inhibitors prevent cancer cells from repairing their DNA, leading to cell death. Olaparib is one such drug that has gained approval for treating metastatic breast cancer with specific genetic mutations.

Advancements in Hormonal Therapies
Hormonal therapy remains a cornerstone in treating hormone receptor-positive breast cancer. Recent advancements aim to overcome resistance to existing treatments.
Selective Estrogen Receptor Degraders (SERDs)
SERDs are a new class of drugs that degrade estrogen receptors, thereby inhibiting the growth of hormone-dependent cancer cells. Drugs like Fulvestrant are being refined to improve their efficacy and oral availability, potentially offering more convenient treatment options.
The Role of Genetic Testing in Personalised Treatment
Understanding one’s genetic makeup is becoming increasingly important in tailoring breast cancer treatment. Genetic tests can identify mutations in genes like BRCA1 and BRCA2, which not only influence treatment choices but also provide information on the risk of developing breast or ovarian cancer.

Advancements in Radiotherapy Techniques
Radiotherapy is evolving with techniques that offer greater precision and fewer side effects.
Proton Beam Therapy
Proton beam therapy uses protons instead of traditional X-rays to treat cancer. This method allows for more precise targeting of tumours, sparing surrounding healthy tissue and reducing side effects. While still being researched for breast cancer, it holds potential for treating complex cases.

Liquid Biopsies: A Non-Invasive Diagnostic Tool
Liquid biopsies involve analysing circulating tumour DNA (ctDNA) in the blood. This non-invasive technique can detect cancer earlier, monitor treatment response, and identify mutations that may cause resistance to therapies.
Early Detection and Monitoring
Liquid biopsies can provide real-time insights into tumour genetics, allowing for timely adjustments in treatment. This approach is especially useful for metastatic breast cancer, where tumour profiles can change over time.

CAR-T Cell Therapy: A Frontier Yet to Be Fully Explored
Chimeric Antigen Receptor T-cell (CAR-T) therapy has shown remarkable success in treating certain blood cancers. Researchers are exploring its application in solid tumours like breast cancer.
Challenges and Opportunities
While CAR-T therapy for breast cancer is still in experimental stages, overcoming challenges such as the tumour microenvironment could make this a viable treatment option in the future.

The Impact of Artificial Intelligence (AI) in Breast Cancer Care
AI is revolutionising healthcare, and breast cancer treatment is no exception. Machine learning algorithms can improve imaging analysis, predict treatment responses, and assist in drug discovery.
Enhanced Imaging and Diagnosis
AI can enhance the accuracy of mammograms by detecting abnormalities that may be missed by the human eye. This leads to earlier diagnosis and improved treatment outcomes.
Nutrigenomics: Diet, Genetics, and Cancer

Nutrigenomics studies the interaction between nutrition and genes. Understanding how genetic variations affect nutritional needs can play a role in cancer prevention and management.
Personalised Nutrition Plans
Through genetic testing like the CircleDNA Premium DNA Test, individuals can receive personalised dietary recommendations. A tailored nutrition plan may support treatment and improve overall well-being.
The Importance of Clinical Trials
Participating in clinical trials gives patients access to cutting-edge treatments and contributes to medical research.
Finding the Right Trial
Resources are available to help patients find clinical trials suited to their condition and location. Discussing options with a healthcare provider is crucial for making an informed decision.

Conclusion
The advancements in breast cancer therapy are a testament to the relentless efforts of researchers and clinicians worldwide. As new breast cancer treatments emerge and existing therapies are refined, patients have more options than ever before. Personalised medicine, powered by genetic insights from tools like the CircleDNA Premium DNA Test, is paving the way for treatments tailored to individual needs.
Staying informed about the latest developments empowers patients and their families to make educated decisions about their health. By combining innovative treatments with preventive strategies, we move closer to a future where breast cancer is not just treatable but preventable.
