What is proton therapy at Mass General?
For many cancer patients the standard treatment for solid tumors is the use of high-energy x-rays. To create these x-rays, medical centers use particle accelerators that propel electrons to tens of millions of electronvolts and then collide them into a metallic target to produce the x-ray spectrum used for cancer treatments.
What does laser light mean in cancer treatment?
Results - Particle Beam Radiation Therapies for Cancer - NCBI Bookshelf. As of December 2007 at least 61,800 patients have received particle beam radiotherapy around the world for various cancers and other diseases. The vast majority (approximately 54,000 or 87%) have received protons. Fewer patients have received radiotherapy with carbon ions (approximately 4,500 or …
Can proton accelerators help treat cancer?
Most types of radiation used for cancer treatment utilize X-rays, gamma rays, and charged particles. As such, they are inherently toxic to all cells, not just cancer cells, and are given in doses that are as efficacious as possible while not being too harmful to the body or fatal.

What is the most effective cancer treatment?
Surgery is an option for most cancers other than blood cancers, with specialized cancer surgeons attempting to remove all or most of a solid tumor. It is an especially effective treatment for early stage cancers that haven't spread to other parts of the body.

What is a photon in radiotherapy?
What is the difference between photon and proton radiation therapy?

What is the purpose of protons in cancer?
In some cases protons can be used to greatly reduce toxic radiation doses to healthy tissue that resides near the tumor, thus reducing treatment side effects. When it opened in 2010, the Northwestern Medicine Chicago Proton Center in Warrenville was the ninth proton cancer treatment center in the United States.
What is the standard treatment for cancer?
For many cancer patients the standard treatment for solid tumors is the use of high-energy x-rays. To create these x-rays, medical centers use particle accelerators that propel electrons to tens of millions of electronvolts and then collide them into a metallic target to produce the x-ray spectrum used for cancer treatments.
Who was the founder of Fermilab?
Physicist Robert Wilson, the founding director of Fermilab, proposed a different cancer treatment method when he published the article “Radiological Use of Fast Protons” in 1946. He suggested using heavy charged particles such as protons to deliver cancer-killing energy to tumors.
How does radiation kill cancer cells?
Radiation therapy kills cancer cells by damaging their DNA inducing cellular apoptosis. Radiation therapy can either damage DNA directly or create charged particles (atoms with an odd or unpaired number of electrons) within the cells that can in turn damage the DNA.
How does radiation therapy work?
Roughly half of all cancer patients receive some form of radiation therapy over the course of their treatment. Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. Radiation therapy kills cancer cells by damaging their DNA inducing cellular apoptosis. Radiation therapy can either damage DNA directly ...
How does nanotechnology help cancer?
The traditional use of nanotechnology in cancer therapeutics has been to improve the pharmacokinetics and reduce the systemic toxicities of chemotherapies through the selective targeting and delivery of these anticancer drugs to tumor tissues.
What is nanotechnology used for?
Additional uses of nanotechnology for immunotherapy include immune depots placed in or near tumors for in situ vaccination and artificial antigen presenting cells. These and other approaches will advance and be refined as our understanding of cancer immunotherapy deepens.
What are the ligands used in nanoparticles?
At the same time, the relatively large surface area of nanoparticle can be functionalized with ligands, including small molecules, DNA or RNA strands, peptides, aptamers or antibodies. These ligands can be used for therapeutic effect or to direct nanoparticle fate in vivo.
What is immunotherapy for cancer?
Immunotherapy is a promising new front in cancer treatment encompassing a number of approaches, including checkpoint inhibition and cellular therapies. Although results for some patients have been spectacular, only a minority of patients being treated for just a subset of cancers experience durable responses to these therapies. Expanding the benefits of immunotherapy requires a greater understanding of tumor-host immune system interactions. New technologies for molecular and functional analysis of single cells are being used to interrogate tumor and immune cells and elucidate molecular indicators and functional immune responses to therapy. To this end, nano-enabled devices and materials are being leveraged to sort, image, and characterize T cells in the Alliance’s NanoSystems Biology Cancer Center.
How does radiation affect DNA?
Radiation therapy can either damage DNA directly or create charged particles (atoms with an odd or unpaired number of electrons) within the cells that can in turn damage the DNA. Most types of radiation used for cancer treatment utilize X-rays, gamma rays, and charged particles.
Does Mass General have proton therapy?
As one of the first hospitals in the world to establish its own proton therapy system, Mass General has an unmatched history in treating both benign and malignant tumors with proton therapy.
Where do protons come from?
Protons are extracted from the particle accelerator and directed with magnetic fields to the tumor . The depth of penetration of the protons is related to their energy and can be precisely controlled to match the location of the tumor. Protons deliver most of their energy to a very narrow volume within the body.
What is the name of the machine that produces X-rays?
It’s called a linear accelerator, or linac for short, and it's a cousin of the Higgs boson-discovering Large Hadron Collider. The other, known as an isotopic teletherapy machine, produces X-rays as silvery cobalt-60 chunks inside a small canister eject X-rays and transform into nickel through radioactive decay.
Can X-rays kill cancer?
Both produce powerful X-rays that can penetrate your skin to kill tumor cells in your body. People from all over Ghana, even outside the country, come to the hospital to use the machines for cancer therapy. “We have patients from Nigeria, Togo, and the Ivory Coast coming to us for treatment,” says Joel Yarney, an oncologist at the hospital.
How many people will die from cancer in 2026?
Cancer, little understood for centuries after it was first named by Hippocrates, often is no longer a death sentence. Yes, some 600,000 Americans will die of a cancer this year. But as of 2016, there were an estimated 15.5 million survivors living in the United States, a number predicted to top 20 million by 2026.
What did Mary Gooding do?
MARY GOODING MADE THIS TRIP alone, listening to NPR as she drove up Interstate 95 in June 2017 on the way from her home in Jamestown, Rhode Island, to Dana-Farber Cancer Institute. On previous trips she’d prayed or chatted with her sister as a distraction. She felt she was through the worst now, six months since an X-ray revealed her persistent cough was caused not by pneumonia or bronchitis, but by a case of melanoma that had reached stage four. Then 60, Gooding knew melanoma well, a byproduct of childhood summers spent poolside at the Warwick Country Club with her eight siblings, even though, she says, “I’m so fair-skinned I get sunburned under a light bulb.” She’d first been diagnosed with the malignant skin cancer in her 40s, and had gone through three surgeries to get rid of various reoccurrences.
How much is Moderna worth?
At $7 billion, Moderna is Boston’s most valuable startup, and one of the most valuable biotech startups in the nation. Another vaccine developer, Neon Therapeutics — spun out of the Dana-Farber lab run by Dr. Catherine Wu — went public in June, hauling in $100 million.
What is the history of Massachusetts?
MASSACHUSETTS HAS AN illustrious history of fighting cancer. In the 1940s, a young Massachusetts General Hospital doctor named Saul Hertz pioneered the use of radioactive iodine to treat patients with thyroid cancer, a precursor of today’s precision medicine.
When did the immune system start?
Using the immune system is an old idea in oncology, stretching back to 1890. The next year, a Harvard-trained surgeon named William Coley treated a patient with sarcoma by injecting him with bacteria to spark an immune response. The patient, considered a hopeless case, lived for eight more years. Advertisement.
